The primary coil of a transformer has N1 = 340 turns, and the
secondary coil has N2 = 2 190 turns. If the input voltage across
the primary coil is Δv(t) = 170 cos ωt, where Δv is in volts and t
is in seconds, what rms voltage is developed across the secondary
coil?

A step-down transformer is used for recharging the batteries of
portable devices. The turns ratio N2/N1 for a particular
transformer used in a CD player is 3:37. When used with 120-V (rms)
household service, the transformer draws an rms current of 125 mA.
(a) Find the rms output voltage of the transformer. V (b) Find the
power delivered to the CD player.

a) An ideal step-down transformer has a primary coil of 400
turns and a secondary coil of 14 turns. Its primary coil is plugged
into an outlet with 240 V(AC), from which it draws an rms current
of 0.35 A. What is the voltage in the secondary coil?
b) Calculate the rms current in the secondary coil.
c) Assuming that the transformer secondary is driving a
resistive load, calculate the average power dissipated in the
resistor.

An ideal step-down transformer has a primary coil of 370 turns

A transformer has a primary-to-secondary turns ratio of 100:1.
The voltage on the primary side is 27.7 kv.a.c. at 60.0 Hz ( assume
60.0 Hz when treating electric power topics). A load is connected
across the secondary winding. Assume that the transformer is
ideal.
(a) Suppose that the electric utility supplied 27.7 kv.d.c.
rather than 27.7 kv.a.c. How much power would the transformer’s
secondary winding deliver to the load in this case?
(b). The transformer’s primary winding is supplied by...
