Chapter 21, Problem 55QAP
Interpretation Introduction

Interpretation:

To determine consumed electrical energy in kilojoules.

Concept introduction:

Faraday’s constant (F) is defined as charge in Coulomb of 1 mole electron.

F=9648×104C

Value of Faraday’s constant is product charge of one electron with Avogadro’s number.

F=Chargeofoneelectron×Avogadro’snumber=1.602×1019C×6.022×1023=9.648×104C

Hence, 1F=9.648×104C

Relation of electrical energy with charge and voltage is,

E=QV

Where, E is electrical energy, Q is charge and V is voltage
