QUESTION: 8

In a two element series circuit, the applied voltage and the resulting current are v(t) = 60 + 66 sin (1000t) V, i(t) = 2.3sin (1000t + 68.3) 3 A. The nature of the elements would be

Solution:

RC circuit causes a positive shift in the circuit.

QUESTION: 9

 P = 269 W, Q = 150 VAR (capacitive). The power in the complex form is

Solution:

S = P – jQ.

QUESTION: 10

Q = 2000 VAR, pf = 0.9 (leading). The power in complex form is

Solution:

 Use cos T = 0.9 or T = 25.84 degrees.
Q = S sin T or S = 4588.6 VA
p = S cos T or P = 0.9 X 4588.6 4129.8 VA.
