What is the equivalent resistance of the circuit shown below if R1 = 15.0 ? and R2 = 17.9 ? ? What current flows through R1? What is the voltage drop across R2? What current flows through R2? How much power is dissipated in R2?

Explanation / Answer

a) Req= 15+15+ [50*17.9/(50+17.9)] =43.2ohm

b) I=V/Req = 24/41.24 = .555A

c) I2 =[ 50/(50+17.9)] * .555 =.409A

V=IR2 = 7.32V

d) I2 =[ 50/(50+17.9)] * .555 =.409A

e) P=V*I =3W
