## What is represented by the E, I, and R in the formula E = IR?

Expert Solution
To determine

The representation of E, I and R, in the formula E=IR.

### Explanation of Solution

Given:

The formula given is E = IR.

Concept used:

According to Ohm's law at a constant temperature, the voltage across a circuit is directly proportional to the current through it.

The given formula, E = IR

It is a mathematical representation of Ohm's law in which the symbol

E = voltage

I = current

R = resistance in the circuit.

Thus, the voltage in a circuit is equal to the current applied multiplied by the resistance.
