Question: In a circuit with two loops, if the current in the first loop is 5 A and the second loop is 3 A, what is the current through a shared resistor of 2 ohms?

Options:

  1. 1 A
  2. 2 A
  3. 3 A
  4. 5 A

Correct Answer: 1 A

Solution: 

The current through the shared resistor is the difference of the currents in the loops, so 5 A - 3 A = 2 A.

Questions & Step-by-Step Solutions

In a circuit with two loops, if the current in the first loop is 5 A and the second loop is 3 A, what is the current through a shared resistor of 2 ohms?
Correct Answer: 2 A
  • Step 1: Identify the current in the first loop, which is 5 A.
  • Step 2: Identify the current in the second loop, which is 3 A.
  • Step 3: Determine that the shared resistor is affected by the difference in currents from the two loops.
  • Step 4: Calculate the difference between the currents: 5 A (first loop) - 3 A (second loop).
  • Step 5: Perform the subtraction: 5 A - 3 A = 2 A.
  • Step 6: Conclude that the current through the shared resistor is 2 A.
