Question

When an AC current passes through a resistor there is dissipation of (A) joule heating (B) electrical energy (C) power (D) Both (a) and (b)

Tardigrade Admin · Accepted Answer

Joule heating is given by i2 R and depends on i2 (which is always positive whether i is positive or negative) and not on i. Thus, there is joule heating and dissipation of electrical energy when an AC current passes through a resistor.

Q. When an $A C$ current passes through a resistor there is dissipation of

joule heating

electrical energy

power

Both (a) and (b)

Joule heating is given by $i^{2} R$ and depends on $i^{2}$ (which is always positive whether $i$ is positive or negative) and not on $i$ . Thus, there is joule heating and dissipation of electrical energy when an $A C$ current passes through a resistor.
