Chapter 34, Problem 7A

How many joules per coulomb are given to charges that flow in a 120-volt circuit?

To determine

To Calculate: The number of joules per coulomb given to charges.

Explanation of Solution

Given:

120-volt circuit

Formula Used:

Relationship between volts and joules per coulomb is as follows:

  $\text{1V}\text{=}\text{1 J/C}$

Calculations:

  $\begin{array}{l}\text{1V}\text{=}\text{1 J/C}\\ \Rightarrow \text{120 V= 120 J/C}\end{array}$

Conclusion:

Thus, $\text{120 J/C}$ are given to charges to flow in 120-V circuit.
