Laboratory #8:

Problems: Phasors

Objectives:

Analyze steady-state AC circuits.

Become familiar with phasors and phasor notation.

In Lab: Work the following problems.

1. Convert the following:

a) Frequency f = 8 kHz to angular frequency ω.

b) Angular frequency ω = 0.5 krad/sec to frequency f.

c) Polar form 10-45° to rectangular form.

d) Rectangular form 3 + j2 to polar form.

e) Sinusoidal function v(t) = 12 cos(377t) to a phasor.

f) Phasor 1510° to a sinusoidal function.

2. Calculate the impedance Z

of the following combinations shown below.

b) frequency = 1 kHz

c) frequency = 20 kHz

d) frequency = 500 Hz

e) frequency = 1 MHz
