Front

States that the current in a circuit equals the voltage difference divided by the resistance.

Back

Ohm's law

Front

The largest (or maximum) instantaneous value in the sine wave is known as:

peak value

Front

Frequency is also known as cycle per second:

Back

True

Front

RMS is calculated by multiplying peak value by ___ .

Back

0.707

Front

What is the unit of electrical power?

Back

watts.

Front

What does RMS stand for in electrical terms?

Back

Root Mean Square.

Front

What is the formula for calculating electrical power?

Back

Power (P) = Voltage (V) x Current (I)

Front

What is the relationship between frequency and period?

Back

Frequency (f) = 1 / Period (T)

Front

What is the effect of increasing resistance in a circuit?

Back

It decreases the current flow.
