A 120-volt circuit has a resistance of 12 ohms.How much current is present in the circuit?
Answer(s): B
A 120-volt circuit has a resistance of 12 ohms. A current of 10 amperes is flowing through the circuit (120 volts divided by 12 ohms = 10 amps).
When the secondary side of a transformer has more turns than the primary side, the output voltage will be ___________ the input voltage.
When the secondary side of a transformer has more turns than the primary side, the output voltage will be higher than the input voltage.
How much power is being carried in a 220-volt circuit when the current is 10 amps?
Answer(s): C
How much power is being carried in a 220-volt circuit when the current is 10 amps? 2,200 watts (220 volts multiplied by 10 amps = 2,200 watts).
Capacitors connected in parallel __________.
Capacitors connected in parallel effectively increase the plate area, which allows for more storage of electrons and more capacity or capacitance.
Another name for a transistor is __________.
The word "transistor" is a shortening of the term "transfer resistor". The transistor's original name when it was invented in 1933 was the "crystal amplifier".
