Question

A step-up transformer has 300 turns on the primaly the secondary current winding and 750 turns on the secondary winding. If the primary current is 2 A, calculate

Answer 1

In a step-up transformer, the secondary voltage is greater than the primary voltage and the secondary current is lower. We can calculate the secondary current using the formula (Primary current x Primary turns) / Secondary turns.

Step-by-step explanation:

In a step-up transformer, the voltage in the secondary winding is greater than the voltage in the primary winding, while the current is lower. The ratio of the number of turns in the secondary winding to the number of turns in the primary winding is equal to the ratio of the secondary voltage to the primary voltage.

Given that the primary has 300 turns and the secondary has 750 turns, and that the primary current is 2 A, we can calculate the secondary current as follows:

Secondary current = (Primary current x Primary turns) / Secondary turns

Secondary current = (2 A x 300 turns) / 750 turns

Secondary current = 0.8 A
