Series-Parallel Circuits - Technical MCQs

Q1:

What is the voltage to the load?

A 11.4 V

B 12.4 V

C 13.4 V

D 15.4 V

ANS:D - 15.4 V

R2 is parallel to RL & inseries with R1=7.155
total current is 35/7.155=4.895
current division rule in between r2& RL4
4.895*7.8/7.8+5.3=2.9
now voltage drop in RL is
2.9*5.3=15.4v
