Voltage and current through a circuit element are given respectively
as: v = (10285)sin(314t + 45°) volts and i = 285 sin(314t + 315°).
Identify the circuit element and find its value. Obtain expression for
power.
Answers
The voltage and current through a circuit element is v= 100 sin (314 t + 45°) volts and i - 10 sin (314 t - 45 ° ) amps.
The type of circuit element and its value will be respectively
a)an inductor with L = 31.8mH
b)a capacitor with C = 10 F
c)an inductor with L = 10 H
d)a capacitor with C = 31.8 μF
Correct answer is option 'A'. Can you explain this answer?
