A step-up transformer has 3000 turns in the secondary coil and 200 turns in the primary coil. The primary is supplied with alternating current with an effective voltage of 90.0 V.
(a) Find the voltage in the secondary coil.
(b) If the current in the secondary coil is 2.00 A, what current flows in the primary coil? (c) What power is developed in the primary coil?
(d) What power is developed in the secondary coil?
