A transformer contains $4800$ turns on the primary coil and $480$ turns on the secondary coil. The primary coil is linked to a $240\ \text{V}$ a.c. supply, and the secondary coil is attached to a lamp. How does the current in the lamp at the output compare with the input current?
- Ahigher frequency a.c.
- Blower frequency a.c.
- Ccurrent in one direction only
- Dthe same frequency a.c.
