Answer:
240 V
Explanation:
number of turns in primary coil, Np = 10 
Number of loops in secondary coil, Ns = 20
Voltage in primary coil, Vp = 120 V 
Let the voltage in secondary coil is Vs. 
So, Vs / Vp = Ns / Np 
Vs / 120 = 20 / 10 
Vs / 120  = 2 
Vs = 240 V
Thus, the voltage in secondary coil is 240 Volt.
