Question

The work done to move 10 coulomb of charge is 200 Jif the current passing through it is 0.2Athe resistance of the wire is

Answer 1

Answer:To solve the task, we have to figure out the potentials in vertices A and B. Then we can enumerate the electric potential energy of the charge Q 3 in these places. The work done by an electric forces by moving the charge from A to B is equal to the difference of these electric potential energies.
