Sheet 4 Solution
Solve the following Problems:
1- Find the current and the power in the R-L circuit shown below.
Solution:
XL=2πf L j
XL=2π50*0.2 j=62.83j Ω
Z=R + j WL
Z=20+62.83j
A
P=120*0.46=55.2 Watt
2- An AC series circuit has RC component in which the capacitance is 100 µF and the
rms voltage is 220 Volts at a frequency of 60 Hz and R=100 Ω.
Capacitive reactance and the rms current.
