A power company transmits current through a 240,000 V transmission line. This voltage is stepped down at an area substation to 40,000 V by a transformer that has 1040 turns on the primary coil. How many turns are on the secondary of the transformer?

1040 * 4/24

=1040 * 1/6
= 173

To find the number of turns on the secondary coil, we can use the formula for transformer turns ratio:

Turns ratio (N) = Voltage on primary coil (V1) / Voltage on secondary coil (V2)

Given that V1 = 240,000 V and V2 = 40,000 V, we can substitute the values into the formula:

N = 240,000 V / 40,000 V = 6

Therefore, the turns ratio is 6. Since the transformer has 1040 turns on the primary coil, we can calculate the number of turns on the secondary coil by multiplying the turns ratio by the number of turns on the primary coil:

Number of turns on the secondary coil = Turns ratio * Number of turns on the primary coil

Number of turns on the secondary coil = 6 * 1040 turns = 6240 turns

Therefore, there are 6240 turns on the secondary coil of the transformer.

To find the number of turns on the secondary coil of the transformer, you can use the formula for the turns ratio:

Turns ratio = (Voltage on primary side) / (Voltage on secondary side)

In this case, the voltage on the primary side is 240,000 V and the voltage on the secondary side is 40,000 V.

Turns ratio = 240,000 V / 40,000 V
Turns ratio = 6

The turns ratio is 6, which means that for every 6 turns on the primary coil, there is 1 turn on the secondary coil.

Since the primary coil has 1040 turns, you can find the number of turns on the secondary coil by dividing the number of turns on the primary coil by the turns ratio:

Number of turns on secondary coil = Number of turns on primary coil / Turns ratio
Number of turns on secondary coil = 1040 turns / 6
Number of turns on secondary coil ≈ 173.33 turns

Therefore, there are approximately 173.33 turns on the secondary coil of the transformer.
