Find the magnitude and direction of the current in the circuit.

Solution

Current flow from higher to lower potential, here current will go from left to right in 6.5 ohm resistance.

Two battery source will add up the voltage.

According to Kirchhoff \'s loop law (voltage law)

14 = 6.5 I + (-11.5) + 10.5 I + 15.6 I

I = (14+11.5)/(6.5+10.5+15.6) = 0.782 ampere
