A lossless transmission line having $50 \Omega$ charateristic impedance and lengh $\lambda / 4$ is short circuited at one end and connected to an ideal voltage source of $1 \mathrm{~V}$ at the other end. The current drawn from the voltage source is

1. $0$
2. $0.02 \mathrm{~A}$
3. $\infty$
4. none of these
