Worksheet 11-Simple AC Circuit Calculations

Question 1

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

Answer 1

The values of resistors are calculated exactly the same for AC and DC circuits.

Question 2

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

Answer 2

Remember to keep the values alike. If a voltage is a peak to peak or RMS, then the mathematics must be done in like units.

Question 3

When a schematic has an AC signal input, what is the symbol?

Answer 3

The AC symbol is a schematic in a circle with an AC sine wave inside.

Question 4

What other forms of resistance can be produced in an AC circuit?

Answer 4

Other forms of resistance in an AC circuit can be those produced by inductors, capacitors or both.

Question 5

Which types of components create reactance in an AC circuit?

Answer 5

Capacitors and inductors produce a resistance to changes in AC flow called reactance.
