There are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.

<h3>Current in the circuit</h3>

The current in the circuit is determined by applying Ohms law as shown below;

V = IR

where;

I is the current
V is the voltage
R is the resistance

I = V/R

At a constant resistance of the circuit, the current in a circuit will increase when the emf of the circuit increases.

Thus, we can conclude that, there are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.
