Ohm's law may be expressed as an equation.

I=E/R Ohm's Law Direct Short Circuit Protection Devices

Correct Answer:

I=E/R

Explanation:

Ohm's law describes how current, voltage, and resistance relate to each other. In its equation form, current equals voltage divided by resistance: I = V / R. If voltage is denoted as E (electromotive force), the same relationship is I = E / R. This form directly shows how current responds to the other two quantities: increase voltage or decrease resistance increases current, and vice versa. The other options aren’t the equation for Ohm's law. The name of the law isn’t the formula, Direct Short describes a fault condition, and Circuit Protection Devices are components, not the mathematical relationship.
