Chapter 14, Problem 14.4P

a)

Interpretation Introduction

Interpretation:

The amount of Current and the number of ${\text{e}}^{\text{-}}\text{/s}$ flow through the circuit has to be calculated.

Concept Introduction:

Electric current:

The quantity of charge that flows in each second through a circuit is called as electric current. Ampere is the unit of electric current and is expressed as A.

A current of one Ampere tells about a charge of one coulomb per second flowing across a point in a circuit.

To calculate the amount of Current and the number of ${\text{e}}^{\text{-}}\text{/s}$ flow through the circuit

b)

Interpretation Introduction

Interpretation:

The amount of joules per heat produced for each electron has to be calculated.

Concept Introduction:

Power:

The work done per unit time is called as Power and its expressed in $\text{Watt(W)}$ and also $\text{J/s}$

The equation of Power is written as,

$\text{P=}\frac{\text{work}}{\text{s}}\text{=}\frac{\text{E}\text{.q}}{\text{s}}\text{=E}\frac{\text{q}}{\text{s}}$ P

Since $\text{q/s}$ = current I, then Power is written as,

$\text{P=E}\text{.I}$

To calculate the amount of joules per heat produced for each electron

c)

Interpretation Introduction

Interpretation:

The number of moles of electrons that will flow through the resistor has to be calculated.

To calculate the number of moles of electrons that will flow through the resistor

d)

Interpretation Introduction

Interpretation:

The voltage that would be required to deliver power to $\text{1}{\text{.00×10}}^{\text{2}}\text{W}$ .

To calculate the voltage that would be required to deliver power
