How to Fix a Light Switch - Light Switch Wiring

How to Fix a Light Switch -  Light Switch Wiring

In our house we have electricity and light bulb. But we don’t know their wiring. It’s simple and easy.
Firstly we draw the wiring diagram; here we used 220 AC volt, 1 switch and one light. this connection also connected to series.
Circuit Required Equipments. One switch. One supply cord.  one light and their holder.

How to Make an Automatic Hand Dryer Circuit - Homemade

How to Make an Automatic Hand Dryer Circuit - Homemade

This is the automatic hand dryer. It’s the simple and very low cost homemade circuit design.  i am focus his electronic circuit but not focus their construction. If you can made the construction of this automatic hand dryer,  more strong and beautiful.  So. 

In this video we make an automatic hand dryer circuit. if you like my video please subscribe my channel. 

 Let’s go firstly  we see the Required Project Components.


 Heater coil 1000 watt , Power Supply Cord , DC  5 Volt Power Supply. DC  12 Volt Power Supply. Transistor BC546 2 pieces , Resistor  100 ohm 2 pieces , LED with Resistor, LDR Resistor, Laser Light , 6 Volt DC Relay 2 pieces , 12 Volt DC Exhaust Fan, Fuse Holder 2 pieces.

Automatic Light Control - Automated Lighting System for Home

automatic Light Control -  Automated Lighting System for Home

This is the simple and cost effective automatic light circuit with light sensing. When power supply is turned OFF, the circuit senses the day light and according to the light it turns on the Lamp. If the light is present even though power fails the circuit turns OFF the Lamp. Here LDR (Light Dependent Resistor) is used to sense the light.

In this video I make a simple and effetely automatic light on off circuit.

Two Way Light Switch Connection - 2 Way Switch Connection Two Way Light...



Two Way Light
Switch Connection- 2 Way Switch Connection- Two Way Light Switch Wiring

Two way switching means having two or more switches in different
locations to control one lamp. They are wired so that operation of either
switch will control the light(s).
A typical application is
that of being able to switch the hall and landing lights on and off from both
upstairs and downstairs. An implementation that allows both lights to be
controlled from both locations could look like this.
In this video I will go to
show you
two way light switch wiring diagram.

How to Dim Lights without a Dimmer - Dim and Bright Lights by using Diode





How to Dim Lights without a Dimmer- Dim and Bright Lights by using Diode.

We are used two light at home 1 dim light and another full bright light, but we easily used 1 light to control grow dim and bright. It is easy and simple to make at home made.

So, in this video I will make a simple light growing control by using a diode. If you like this video please subscribe my channel?

Transformer Testing - Transformer Test and their Procedure

Transformer Testing  - Transformer Test and  their Procedure

For confirming the specifications and performances of an electrical power transformer it has to go through numbers of testing procedures. Some tests are done at manufacturer premises before delivering the transformer. Mainly two types of transformer testing are done at manufacturer premises- type test of transformer and routine test of transformer. In addition to that some transformer tests are also carried out at the consumer site before commissioning and also periodically in regular & emergency basis through out its service life.


In this video we will learn type of transformer testing in manufacturing commissioning and installation period and their procedure.

Working of Fan with Circuit Diagram - Construction of Ceiling Fan Motor





Working of Fan with Circuit Diagram  - Construction of Ceiling Fan Motor

A ceiling fan is a mechanical fan, usually electrically powered, suspended from the ceiling of a room, that uses hub-mounted rotating paddles to circulate air.

Casablanca Fan Co. "Delta" ceiling fan from the early 1980s.
Most ceiling fans rotates much more slowly than most electric desk fans; it cools people effectively by introducing slow movement into the otherwise still, hot air of a room. Fans never actually cool air, unlike air-conditioning equipment, but use significantly less power (cooling air is thermodynamically expensive). Conversely, a ceiling fan can also be used to reduce the stratification of warm air in a room by forcing it down to affect both occupants' sensations and thermostat readings, thereby improving climate control energy efficiency

•    An electric motor (see Types of ceiling fans below for descriptions)
•    Blades (known as paddles or wings) usually made from wood, plywood, iron, aluminum, MDF or plastic
•    Blade irons (alternately blade brackets, blade arms, blade holders, or flanges), which hold the blades and connect them to the motor.
•    Flywheel, a metal or tough rubber double-torus which is attached to the motor shaft, and to which the blade irons may be attached. The flywheel inner ring is locked to the shaft by a lock-screw, and the blade irons to the outer ring by bolts that feed into tapped metal inserts. Rubber or plastic flywheels may become brittle and break, a common cause of fan failure. Replacing the flywheel may require disconnecting wiring and requires removing the switch housing that's on the way for the flywheel to be removed and replaced.
•    Rotor, alternative to blade irons. First patented by industrial designer Ron Rezek in 1991, the one-piece die cast rotor receives and secures the blades and bolts right to the motor, eliminating most balance problems and minimizing exposed fasteners.
•    A mechanism for mounting the fan to the ceiling such as:
•    ball-and-socket system. With this system, there is a metal or plastic hemisphere mounted on the end of the downrod; this hemisphere rests in a ceiling-mounted metal bracket and allows the fan to move freely (which is very useful on vaulted ceilings). Some companies have come up with slight modifications of this design.
•    J-hook (Claw hook) system. a type of mounting system where the ceiling fan hangs on a metal hook, attached to the ceiling. A rubber grommet is used to keep the fan in place and helps avoid vibration on the ceiling.
•    Some fans can be mounted using a low-ceiling adapter, a special kit which must be purchased from the fan's manufacturer. This eliminates the need for a downrod, and is therefore useful in rooms with low ceiling clearance.
•    In recent years, it has become increasingly common for a ball-and-socket fan to be designed such that the canopy (ceiling cover piece) can optionally be screwed directly into the top of the motor housing; then the whole fan can be secured directly onto the ceiling mounting bracket. This is known as a "close-to-ceiling" mount.
