Since electrons are negatively charged so they move towards the positive end of the battery i.e. electronic current is from negative potential to positive potential. And conventional current flows in opposite direction i.e. from positive potential to negative potential.

So, the potential is positive in the direction against the direction of electric current and it is negative in the direction of electric current.

# A cell of emf E and internal resistance r is connected to two external resistance R1 and R2 and a perfect ammeter.The current in the circuit is measured in four different situation: (i)without any external resistance in the circuit (ii)with resistance R1 only (iii)with Ri and R2 in series combination (iv)with R1 and R2 in parallel combination The currents measured in the four cases are 0.42A,1.05A,1.4A and 4.2A,but not necessarily in that order.Identify the currents corresponding to the four cases mentioned above.
