Express your answer using two significant figures.

Answer

Potenti als at points a,b,c,d be Va, Vb, Vc, Vd respectively.

The potential at the lower right point which is c is zero that is Vc = 0 V

Apply Kirchoff’s loop rule

i = 2 A

Here, i is the current through the circuit.

Here, Va– Vc = 5V

Va – 0 = 5V

Va = 5V

The expression for the potential difference between the c and b is

..8..

Thus, potentials at a and b are 5V and -2V respectively
