Question

Which expression gives the sinusoidally varying voltage applied by the AC source?

Options

• \[v=v_m\sin\omega t\]

• \[v=iR\]

• \[v=\frac{q}{C}\]

• \[v=L\frac{di}{dt}\]

Answer 1

The AC source applies a sinusoidally varying voltage given by \[v=v_m\sin\omega t\]. The other expressions are individual terms in the circuit equation.
