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?

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.

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
