Question

A transformer has 500 volts applied to the primary side and 10,000 volts are measured

on the secondary side. If 10mA is applied to the primary side. What is the anticipated
current on the secondary side? Is this a step-up or step down transformer?

Answer 1

0.5 mA, step-up transformer

Step-by-step explanation:

Power is constant

V * I = constant

500 V * 10 mA = 10,000 V * I

so I = 0.5 mA

From 500 V increases to 10,000 V, so it is a step-up transformer
