Question

In a given conductor, force per charge is equal to 10N/columb. total length of conductor is 100meters. charge per sec is 10columb/sec. then work done per sec?

Answer 1

I found: `10,000J/sec`

Explanation:

Well, analyzing the units you should have:
`10N/cancel(C)*100m*10cancel(C)/(sec)=10,000Nm/(sec)=10,000J/sec` that is in units of work per second.

From what I understand in your wire (of `100m` length) you have a fileld or force per coulomb that moves 10 coulombs every seconds along it....I think.

Answer 2

10kilowatts

Explanation:

Determination of voltage:

Electric Field Intensity=Force/charge

But Voltage=Electric Field Intensity x length

Therefore

Voltage=(Force/charge )x length

`V=F/QxxL`

`V=10xx100`

`V=1000`volts

Determination of current:

`I=Q/t`

Where Q=charge ; t=time.

`I=10`Amperes

Determination of power:

`P=VI`

P=power=work done/sec

`P=10xx1000`

`P=10000`watts
