Question

What does Kirchhoff's Voltage Law give when the only element connected to the AC voltage source is resistor \[R\]?

Options

• \[v=I_{\mathrm{rms}}^{2}R\]

• \[v=iR\]

• \[v=\frac{i}{R}\]

• \[v=i_mR^{2}\]

Answer 1

With only resistor \[R\] in the circuit, the applied voltage equals the voltage across it. Thus Kirchhoff's Voltage Law gives \[v=iR\].
