Will a photocell work using dc voltage?
it creates a dc current
When transformer voltage regulation will be zero it operate at?
A transformer will operate with a voltage regulation of zero when it is not supplying a load.
What are transformers designed to operate with?
to step up voltage or to step down voltage
How do you connect Two DC generators together to double the output voltage?
You would connect them in series to double the output voltage.
What is the highest voltage rated breaker an electrician can operate?
An electrician does not operate breakers he installs them.
Will a photocell work using dc voltage?
it creates a dc current
Why do light bulbs glow differently in a series circuit than in a parallel circuit?
Lamps will only operate at their rated power when subjected to their rated voltage -which is why you will see both figures shown on the glass envelope (e.g. 60 W / 230 V or 60 W / 120 V, etc.). If you connect lamps in parallel, because each branch is subject to the same voltage (i.e. the supply voltage), each lamp has the same voltage applied and will operate at its rated power. If you connect lamps in series, the supply voltage will distribute itself as a series of voltage drops where the sum of the voltage drops will equal the supply voltage. So none of the lamps is subject to its rated voltage, so none will operate at its rated power -i.e. they will be dim!
When voltage regulation will be zero it operate it?
A transformer will operate with a voltage regulation of zero when it is not supplying a load.
When transformer voltage regulation will be zero it operate at?
A transformer will operate with a voltage regulation of zero when it is not supplying a load.
Compare an anode and a cathode?
The Anode (+) is what you connect the positive voltage to The Cathode (-) is what you connect the negative voltage to.
Can you connect a 277V ballast to 208V line service?
No. A 277 volt ballast needs the correct voltage to operate. The 277 voltage is derived from the star point voltage of a 480 volt three phase system (277/480). The 208 voltage is a three phase line voltage whose star-point voltage is 120 volts (120/208).
How do you test for short to voltage?
The following procedure tests for a short to voltage in a circuit.1. Set the rotary dial of the DMM to the V(DC) position.2. Connect the positive lead of the DMM to 1 end of the circuit to be tested.3. Connect the negative lead of the DMM to a good ground.4. Turn ON the ignition and operate all accessories.5. If the voltage measured is greater than 1 volt there is a short to voltage in the circuit.
What are transformers designed to operate with?
to step up voltage or to step down voltage
What happen to lamp if over voltage?
A lamp will only operate at its rated power if it is subjected to its rated voltage. Increase that voltage will increase the power of the lamp -in other words, it will operate more brightly. This is how 'photoflood' lamps operate -they are deliberately designed to operate at overvoltage. Of course, this reduces the life of the lamp.
How do you connect Two DC generators together to double the output voltage?
You would connect them in series to double the output voltage.
What voltage does an electric train operate?
25000v
On what voltage do the 8085 and 8086 operate?
The 8085 and 8086/8088 operate on 5 volts.
