Question

The heat developed in a current carrying conductor is directly proportional to the square of:

• A. Resistance
• B. current
• C. Time
• D. Voltage

Answer 1

Answer:

B. current

• The heat developed in a current-carrying conductor is directly proportional to the square of the current flowing through it.

• This relationship is described by Joule's Law of Heating. The law states that the heat (H) produced in a resistor is proportional to the square of the current (I), the resistance (R), and the time (t) for which the current flows.

• H=I²RT
