Worked practice questions

Electric current is defined as:

  1. Charge / time
  2. Charge × time
  3. Time / charge
  4. Voltage × charge
Show answer and solution

Correct answer: A. Charge / time

Current I = Q/t, where Q is total charge that flows in time t. **SI unit:** ampere (A) = coulomb per second.

Ohm's law relates V, I, R as:

  1. V = I + R
  2. V = I × R
  3. V = R / I
  4. V = I − R
Show answer and solution

Correct answer: B. V = I × R

**Ohm's law:** V = IR. The current through a metallic conductor is directly proportional to the potential difference across it at constant temperature.
