Post Q&A demo

1. What is Ohm’s Law?

Ohm’s Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). Formula: I = V / R

2. What is the purpose of a transformer?

A transformer is used to increase (step-up) or decrease (step-down) the voltage level in an AC circuit while maintaining the same frequency.
