An ideal transformer has 50 turns in its primary and 250 turns in its secondary. 12 V ac is connected to the primary. Find:

a. The voltage ac available at the secondary.

b. Current in the 10 ohms device connected to the secondary.

c. Power supplied to the primary.

d. Power supplied to the secondary.

Solutions

Expert Solution

a) Let the voltage ac available at the secondary is V_s.

Given that the primary ac voltage V_p=12 V.

The primary turns N_p=50 Turns.

The secondary turns N_s=250 Turns.

We know from the transformer principles

The voltage ac available at the secondary is 60 V.

b) Let the current in the device connected to the secondary is I_s.

Given that the resistance of the device R_s=10 Ohms.

The secondary ac voltage V_s=60 V.

The current in the device is

The current in the device connected to the secondary is 6 A.

c) Let the power supplied to the primary is P_p.

The ac voltage connected to the primary is V_p=12 V.

Let the current in the primary is I_p.

The current to the primary is

The power supplied to the primary is

The power supplied to the primary is 360 Watts.

d) Let the power supplied to the secondary is P_s.

The current in secondary is I_s=6 A.

The voltage in secondary is V_s=60 V.

The power supplied to secondary is

The power supplied to secondary is 360 Watts.
