If three resistors of 2 Ohms, 3 Ohms, and 5 Ohms are connected in series, what is the current through the 3 Ohm resistor when connected to a 20V battery?
A2 A
B3 A
C5 A
D20 A
✓ Correct Answer: A — 2 A
Total R = 2+3+5 = 10 Ohms. Total Current I = V/R = 20/10 = 2A. In series, current is same everywhere.
