If 20V battery in the left side and 10V battery to the right side (both cases the positive voltage is on the upside) is applied to a resistive circuit of 10Ω.
What will be the value and conventional direction of the current?
From left to right with 3 Amps. From right to left with 1 Amps. From left to right with 1 Amps. From right to left with 10 Amps.
