Chapter 2, Section 4 & 5

Question 1

Are resistors calculated differently in an AC circuit when compared to an equivalent DC one, why or why not?

Answer 1

Yes, because of impedance. AC circuits have both resistance and reactance.

Question 2

What is the rule to remember when calculating the AC voltages in your final circuit outcome?

Answer 2

Use vector addition for both magnitude and direction.

Question 3

Define phase as it refers to the timing of two AC signals.

Answer 3

Relative timing or position of two AC signals.

Question 4

At what phase would two signals exactly cancel each other out?

Answer 4

180 degrees out of phase.
