According to Ohm's Law, current is equal to what?

Ohm's Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor. Mathematically, it is expressed as I = V/R, where I is the current, V is the voltage, and R is the resistance.

This means that to find the current in a circuit, you take the voltage (the electrical potential that drives the current) and divide it by the resistance (which impedes the flow of current). Therefore, option B, which states that current is equal to voltage divided by resistance, accurately reflects this fundamental principle of electrical circuits. Understanding this relationship is crucial for anyone studying electrical concepts in beauty therapy, especially in treatments that involve electrical equipment.
