Which of the following is true for Ohm’s law?
  1. Ohm’s law states that a steady increase in voltage should reduce the magnitude of current through the circuit that has constant resistance.
  2. Ohm’s law states that a steady decrease in voltage should increase the magnitude of current through the circuit that has constant resistance.
  3. Ohm’s law states that a steady decrease in voltage should increase the magnitude of current through the circuit and increase the resistance offered by the circuit.
  4. Ohm’s law states that a steady increase in voltage should produce a constant and linear increase in current through the circuit that has constant resistance.
Explanation
Answer - D - Ohm’s law states that a steady increase in voltage should produce a constant and linear increase in current through the circuit that has constant resistance.

Key Takeaway: Ohm’s law defines a relationship between power, voltage, current, and resistance. It is the primary law electrical theory is based on.
