Question

What does the term “ohmic loss” refer to?

Options

• Power converted into kinetic energy only, given by \[P = \frac{V^2}{R}\].

• Potential energy stored in charges, given by \[P = IV\Delta t\].

• Electrical power converted into heat in a resistor, given by \[P = I^2R\].

• Charge passing through a resistor, given by \[P = I\Delta t\].

Answer 1

Ohmic loss is the electrical power converted into heat in a resistor. Its expression in terms of current and resistance is \[P = I^2R\].
