Question

current flowing through a 20 ohm resistor is i(t)=4+5sinwt-3coswt where t =time period w =angular frequency find the power consume by resistor​

Answer 1

Answer:

here's your answer

Total Resistance=30+20 =50 ohms

Since,V=I ×R (ohms law)

=> I=V/R =10/50 =0.2 A

For P.D. across 30 ohm----

since , V=I R

V=0.2× 30

V= 6 volts

hope it's help
