A transformer has 1800 primary turns and 120 secondary turns. The input voltage is 120b and the output current is 8.0A. what is the secondary voltage and primary current
To find the secondary voltage, we can use the formula:
secondary voltage = (turns ratio) * input voltage
The turns ratio is given by:
turns ratio = secondary turns / primary turns
Using the given values:
turns ratio = 120 secondary turns / 1800 primary turns
= 1 / 15
Thus, the secondary voltage is:
secondary voltage = (1 / 15) * 120 V
= 8 V
To find the primary current, we can use the formula:
primary current = (output current) * (turns ratio)
Using the given values:
primary current = 8.0 A * (1 / 15)
= 0.533 A
