In an ideal transformer, the voltagae and the current in the primary coil are 200V and 2 A, respectively. If the voltage in the secondary coil is 200 V, then the value of current in the secondary coil will be

A

0.2A

B

2A

C

10A

D

20A

Text Solution

Verified by Experts

The correct Answer is:
A

Given
Voltage in primary coil, `(V_P)=200 V`
Current in primary coil, `(i_P)=2A`
Voltage in secondary coil, `(V_S)=2000 V`
The relation for the current in the secondary coil is
`(V_s)/(V_P)=(i_P)/(i_S) implies (2000)/(200)=(2)/(i_S) =((2 xx 200)/(2000)=0.2 A`.
