Answer :
You have a potential difference of 9 v. The amount of work done to transfer 0.33 c of charge through it is (w)= 2.97 Joule.
What is work done?
When a current pass through a wire, the wire trying to stop the current flow. Then you have to give some amount of force from outside to help the current flow. That is called the work done by the current. It can be measured in Joule.
How can we measured the work done?
To calculate the work done we are using the formula here is,
w= qv
Here we are given,
q= The charge of the current. = 0.33 C.
v= The potential difference of the current. =9 Volt.
We have to calculate the work done by the current. = w Joule.
Now we put the values in above equation,
w= qv
Or, w=0.33*9
Or, w= 2.97 Joule.
So we can say that, The amount of work done is (w)= 2.97 Joule.
