Question

Turn ratio in a setup transformer is 1: 2.If a lechlanche cell of 1.5 V is connected across the input, what is the voltage across the output?

• A. 1.5 v
• B. 0.0 v
• C. 3 v
• D. 0.75 v

Answer 1

The correct option is C 3 v

$\frac{n_1}{n_2}=\frac{V_1}{V_2}⟹\frac{1}{2}=\frac{1.5}{V_2}⟹V_2=3V$
