What size breaker do you need for 3kva?
To calculate an answer a voltage must be stated.
Why bulbs connected inparallel?
all the bulbs must in parallel because all must get the same voltage.......in parallel voltage is constant.if they are connected in series they will not get same voltage
What type of voltage must be connected to a d'arsonval meter movement?
dc voltage
What type of voltage must be passed across a transformer?
A transformer must be connected to an alternating current (AC) supply of the correct voltage.
How can you obtain three time voltage across potential coil of wattmeter?
The voltage applied to the voltage coil of a wattmeter must not exceed the voltage rating of that coil.
True or False The voltage rating of a fuse can be greater than the circuit voltage?
True. The voltage rating of a fuse must be greater than the circuit voltage.
How must the voltage across a resistor change to reduce the current in the resistor by a factor of 3?
The voltage must reduce by the same factor - that is Ohm's law.
What is the voltage drop on a 220 watt bulb?
To answer this question the systems voltage on the bulb must be known.
Can you charge a 18v battery with a 12v charger?
NO, voltage of the charger must match the battery voltage.
Are resistor drops the voltage or current?
Are resistor drops the voltage or current? ANSWER: The voltage DROP is a way to imply that the voltage no matter of the value is what it must be whether it is measured or calculated
The voltage drop in line can be decreased by?
The voltage drop in a line can be decreased by
What is the voltage loss over 400 feet?
To answer this question the supply voltage and the amperage of the load must be given.
