AC Circuits
Exampie: An AC source has an output rms voltage of 78.0 V at frequency of 80.0 Hz. If the
source is connected across an 25.0 mH inductor, what are: (a) the inductive reactance of the
circuit, (b) the rms current in the circuit, and (c) the max
A series RLC circuit has R = 250 Q, L = 0.6 H, and C = 3.5 uF. It is connected to an AC source with
f= 60.0 Hz and Ema, = 150 V
Calculate the average power delivered to the circuit.

Calculate the maximum voltages across (a) the resistor, (b) the inductor and (c) the capacitor.
Solution:
We rst determine the reactances of the circuit. The capacitive reactance is

RLC Series Circuit
Because R, L and C are in series, the current through
all elements must be the same at any instant of time.
However, voltages across each element have different
amplitudes and phases.
For AC circuits, it is very convenient to use vector

Semiconductors
When N atoms combine into solid, atomic energy
levels such as 1s, 2s, 2p, 3s, etc., become energy
bands, each consisting of N closely spaced energy
levels.
