If a circuit has 24 volts and a resistance of 6 ohms, what is the current?

Correct answer

4 amps

  1. A 144 amps
  2. B 4 amps
  3. C 30 amps
  4. D 18 amps

Why this is the answer

The current is 4 amps. Using OHM'S LAW (I = V ÷ R): I = 24 volts ÷ 6 ohms = 4 amps. ASVAB Electronics Information tests Ohm's Law calculations. Rearranging V = I × R to solve for current: I = V ÷ R. Plug in the values: 24 ÷ 6 = 4. Always identify what you're solving for (current here) and use the correct form of the formula. These calculation questions are common — practice rearranging V = I × R to find any of the three quantities given the other two.
