Textbook Question
Chapter 15, Problem 1RQ
- What is represented by the E, I, and R in the formula E = IR?
Expert Solution & Answer
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.
