Explanation
Within a series circuit, the total voltage (or electromotive force) is the sum of all individual cell's voltages. In this case, the total voltage provided to the circuit is given by three cells, each offering 1.5 V, hence a total of 4.5 V (from 1.5 V * 3). That total voltage operates to uphold the current flow within that complete circuit. If one cell is taken out, the total collaborative voltage provided to the circuit decreases. It reduces down to 3 V (2 remaining cells).Therefore, current in the circuit will decrease according to Ohm's Law which states that the current in a circuit is directly proportional to the voltage (as the voltage decreases, so does the current) and indirectly related to the resistance (assuming the resistance within the circuit holding equal).
