Series-Parallel Circuits

If the voltage between points A and B equals 9 V in the given circuit, then V_R3 equals ______.

A 0.9 V

B 8.1 V

C 9 V

D More information is needed to find V_R3.

ANS:B - 8.1 V

Total resistance is 90(parallel)+10(both are in series) = 100.
From this total current is 9/100 = 0.09.

Voltage drop across 10 ohm is 10*0.09 = 0.9.
Voltage after 10 ohm is 9-0.9 = 8.1v.
