A lossless transmission line having 50 Ω characteristic impedance and length λ⁄4 is short circuited at one end and connected to an ideal voltage source of 1V at the other end. The current drawn from the voltage sources is (a) 0 (b)0.02 A (c) ∞ (d)None of the these |

Answer» Correct option (a) 0 Explanation: For quarter wave transformer (λ⁄4) zin = z20/zL zL = 0 (short circuit) zin = z20/0 = ∞ (open circuit) The current drawn from the voltage source Is = Vs/zin = Vs/∞ = 0 |
