Question 27

Current Electricity

Three 5 ohm resistors connected in parallel have a potential difference of 60 V applied across the combination. The current in each resistor is

  1. A.4 A
  2. B.36 A
  3. C.12 A
  4. D.24 A
  5. E.10 A.
Show the answer and explanation

Answer: C (12 A)

Explanation

In parallel each resistor has the full 60 V across it, so I = V/R = 60/5 = 12 A.
