Question

Where is alternating voltage \[V_p\] applied?

Options

• Across the secondary coil with \[N_s\] turns

• Across the silicon-steel laminations

• Across the laminated soft iron core

• Across the primary coil with \[N_p\] turns

Answer 1

Alternating voltage \[V_p\] is applied across the primary coil. That coil has \[N_p\] turns and is connected to the AC source.
