A step-down transformer has a turns ratio of 1:10 and its primary is connected across the terminals of a standard 120 V wall socket. A 330 ohm resistor is connected across the secondary of this transformer. What power P is dissipated in the resistor?

The secondary voltage is 120/10.
Power= secondaryvoltage^2/R
Power= secondaryvoltage^2/R
