Chapter 19, Problem 19.7QP

Interpretation Introduction

Interpretation:

The SI unit of energy as the product of two electrical units should be expressed.

Concept introduction:

SI unit:

The acceptable units of any measurable quantity is given by system international is known as SI unit.

SI unit of Energy:

Electrical potential:

Without producing any acceleration, work needed to move a unit of positive charge from infinite to reference point against the electrical charge is known as electrical potential.

Therefore the electrical potential is,

$\text{Volt=}\frac{\text{Joule }}{\text{Coulomb}}$

Hence the energy is,

$\text{Joule}\text{=}\text{Coulomb×}\text{Volt}$
