To find the potential difference per turn in the transformer, we need to understand the primary and secondary voltage relationship. Given that the transformer has a high efficiency, we will assume it's ideal for simplicity.
The transformer formula relating the number of turns and the voltage in primary and secondary windings is given by:
‌=‌Where:
Vp is the primary voltage
Vs is the secondary voltage
Np is the number of turns in the primary winding
Ns is the number of turns in the secondary winding
Given:
‌Vp=220V‌Np=200‌Ns=40000 We need to find
Vs, the secondary voltage. Rearrange the formula to solve for
Vs :
Vs=Vp×‌Substitute the given values:
Vs=220V×‌Calculate
Vs :
Vs=220V×200=44000V Now, we need to find the potential difference per turn. For an ideal transformer, this is the same for both primary and secondary because the voltage per turn is consistent in an ideal transformer. We can use the primary coil to find this:
Potential difference per turn (in primary) is:
‌Substitute the values for
Vp and
Np :
‌=1.1V‌ per turn ‌Therefore, the potential difference per turn is:
Option D: 1.1 V
