PHY 102 Current Electricity Objective Question

Question

Three 5-ohm resistors connected in parallel have a potential difference of 60V applied across the combination. What is the current in each resistor? (Based on Assignment 13.14)
Options
A 4A
B 36A
C 12A
Correct Answer
D 24A
Correct Answer

Option C is the correct answer.

Detailed Explanation

For resistors connected in parallel, the potential difference (voltage) across each individual resistor is the same as the total potential difference applied across the entire parallel combination. Therefore, the voltage across each 5 Ω resistor is 60 V. Using Ohm's Law (I = V/R), the current in each resistor is I = 60 V / 5 Ω = 12 A.

Hint

Remember the fundamental property of parallel circuits: voltage is the same across all parallel components.
