5 Questions
Question 1 of 5
What is the unit of measurement for AC power?
Watts measure real power consumed by a circuit.
Question 2 of 5
What does 'AC' stand for in electrical circuits?
AC stands for Alternating Current, where current flow reverses direction periodically.
Question 3 of 5
Which of the following is the formula for calculating AC apparent power (S)?
Apparent power (S) is calculated as the product of voltage and current.
Question 4 of 5
In a purely resistive AC circuit, what is the phase relationship between voltage and current?
In a resistive circuit, voltage and current are in phase.
Question 5 of 5
What is the power factor in an AC circuit with purely reactive components (inductors or capacitors)?
Reactive components consume no real power, thus the power factor is zero.
