Question

Which of the following best describes DC and AC circuits. Pick all that are correct. This question may be worth 2 points. DC circuits can only have constant currents. DC circuits have direct currents whose directions do not change with time. DC circuits can have both constant and non-constant currents. AC circuits have electrical currents whose magnitude and direction change cyclically with time. DC circuits always have only non-constant currents. AC stands for additional currents which means that the circuit consists of multiple current sources.

Explanation / Answer

DC circuits have direct currents whose directions do not change with time AC circuits have electrical currents whose magnitude and direction change cyclically with time DC circuits can only have constant currents
