Series AC Circuits

The time of a periodic waveform is called a period.

• True

• False

Increasing the frequency of a waveform increases the period.

• True

• False

For an inductor, the voltage leads the current through it by 90°.

• True

• False

For a capacitor, the current lags the voltage through it by 90°.

• True

• False

For an inductor, the voltage leads the current through it by 90°.

• True

• False

Impedance is the combination of capacitive reactance, inductive reactance, and dc resistance.

• True

• False

What is the total impedance ZT of a series network consisting of a 5 Ω resistor, an inductor having 10 Ω reactance, and a capacitor with 15 Ω reactance?

• 5 Ω + j 25 Ω

• 5 Ω - j 25 Ω

• 5 Ω - j 5 Ω

• 5 Ω + j 5 Ω
