O When battery cells are in parallel, the voltage stays the same and the cells last longer O When battery cells are in parallel, the voltage increases, but the cells last the same amount of time. when battery cells are in parallel the voltage is the same and they last just as long as when the cells are in Series. 0 when battery cells are in series, the voltage stays the same but the cells last longer. O When battery cells are in series, the voltage increases and the cells last longer. KFT 21 MC.004 What is electric current? the electrical energy from by a battery 0 the same thing as a charge O an abrupt and brief electrical discharge, such as a spark e) a continuous flow of charge the electrical energy from a generator

Explanation / Answer

2) First option is correct.

When batteries are connected in series, voltage across them remains same. But the power is increased which means the batteries will last longer.

When connected in series, the voltage is increased but they don't last longer.
