Question

A circuit consist of a non indective resistance of 50 ohms,an indectence of 0.3 henry and a resistence of 2 ohms and a capacitance of 40microfarad in series and the supply voltage is 200 volts at 50 hertz find a)impedence b)current c)power in the circuit

Answer 1

Answer:

Impendence

√R2+(XL-XC)2

√(52)2 +(30π-250/π) 2

√2704+(94.2-79.6) 2

√2916.6~54ohm

current:

v/z=200/54=3.7A

power in the circuit :

R/z=52/54=0.94
