Answer:
<h2>
Work done by the gas is given as</h2><h2>

</h2>
Explanation:
As we know that the process is isothermal so here work done is given as

here we know that


now we have

so we have

1) using kirchhoff voltage and current law.
2) voltage and current divider rule
3) ohm's law
Static electricity is caused by the build up of charges on surfaces of objects while electric current is the constant flow of electrons along a conductor (the rate of flow of charge).
