What is the relationship between voltage, current, and resistance in an electrical circuit?

Back

Ohm's Law states that Voltage (V) = Current (I) × Resistance (R).

Front

What is the difference between alternating current (AC) and direct current (DC)?

Back

AC changes direction periodically, while DC flows in one direction.
