Need more info to give you the most usefull answer. However, generically speaking, sounds like what you need is a 120v relay. Put the relay output contacts in series with the fan (aka the load) then wire the relay coil in parallel to the light bulb power. This will make the load come on when the light is powered on. Tip, if the fan is driven by an induction motor (most are, if it has brushes it is NOT an induction motor) then your speed controller will have to be the kind for an inductive load ( NOT the kind for a resistive load, like a lightbulb ). Good luck.
AnswerA solid state relay, or SSR should do it for you. SSRs take a broad range of input voltage as you require, and have snubbers to allow them to switch inductive loads such as the fan.To de-energize a circuit, the voltage has to be cut off at the source. This is usually done with a disconnect switch which is located just before the circuit's load. Turning off the breaker on a distribution panel will de-energize the circuit it is feeding. To make sure that the voltage can not be turned back on when work is being done on the circuit, the switch or breaker must have a lock off device to prevent the circuit from being turned on, except by the person that locked the circuit off.
Light bulbs connected in parallel automatically have "the same voltage applied to them".
De energising means you are disconnecting a device from electricty source. Switch off the device, physically disconnect the device to de energise the circuit.
Line voltage is understood as the voltage that the device or appliance needs to operate on. It is also referred to as the devices working voltage. Once the proper line voltage or working voltage is applied to the device it may be transformed to different voltages for different internal component circuits.
when no electricity flow then chare are in condition of static
Any voltage that is fed into or "applied" to an electrical circuit is referred to as an "applied voltage".
The 8051 runs on +5vdc.
A: To read ohms you will use it by reading in parallel and without any external voltage applied
The voltage is greater than the applied voltage, why?
No current flows when the applied voltage is zero.
For a series circuit, the applied voltage equals the sum of the voltage drops
The Anode (+) is what you connect the positive voltage to The Cathode (-) is what you connect the negative voltage to.
Current is directly proportional to applied voltage. Ohm's law.
sending voltage means voltage applied to source side.....
The applied voltage is 53+28 = 81V.
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
A: As soon as a DC voltage is applied the capacitor is a short or no voltage
