Practice question

Which standard electrical formula describes the relationship between voltage, current, and resistance in a circuit?

  1. Ohm's Law: V = I * R (Voltage = Current * Resistance)
  2. Newton's Law: F = M * A (Force = Mass * Acceleration)
  3. Watt's Law: P = V / I (Power = Voltage / Current)
  4. Pascal's Law: P = F / A (Pressure = Force / Area)

Answer: A — Ohm's Law: V = I * R (Voltage = Current * Resistance)
