A transformer connected to a 120 −V ac line is to supply 12.0 VV
(rms) to a portable electronic device. The load resistance in the
secondary is 5.20 ΩΩ .

connected directly across the source line (which has a voltage of
120 −V) would draw the same power...

An ideal step-down transformer has a primary coil of 370 turns
and a secondary coil of 25 turns. Its primary coil is plugged into
an outlet with 115 V(AC), from which it draws an rms current of
0.69 A.

Calculate the rms current in the secondary coil.
Assuming that the transformer secondary is driving a resistive
load, calculate the average power dissipated in the resistor.

A step-up transformer has a primary coil with 100 loops and a

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.

A transformer has 500. primary turns and 10.0 secondary turns.
(a) If Vp is 120.V(rms), what is Vs? If the secondary now has a
resistive load of 10.0Ω, what is the current in the (b) secondary
and (c) primary? (Hints: Input power equals the output power.
Express power in terms of voltage and current, then use Faraday’s
Law to relate voltage to number of turns and change of flux. If the
primary and the secondary are connected via a closed...

An ideal transformer has 100 turns on its primary coil and 200
turns on its secondary coil. If 120 V at 2.0 A is applied to the
primary,

(b) What current is present in the secondary?
(c) What is the output power?
(d) Is this a step-up or step-down transformer?
(e) Is the input power the same, larger or smaller than the
output power?

An AC adapter for a telephone answering machine uses a
transformer to reduce the line voltage of 120 V to a voltage of
4.00 V. The RMS current delivered to the answering machine is 350
mA. If the primary (input) coil of the transformer has 720 turns,
then how many turns are there on the secondary (output) coil?
What is the power drawn from the electric outlet, if the
transformer is assumed to be ideal?
What is the power drawn...
