What do DC cells connected in series form?

• A. Capacitor
• B. Inductor
• C. Battery
• D. Resistor

Answer: (C)

When DC cells are connected in series, their voltages add up to create a higher voltage source. This arrangement essentially forms a battery or battery pack, because you’re combining multiple cells to act as a single source of electrical energy. The total voltage is the sum of the individual cell voltages, while the current-capacity (the ability to deliver current over time) remains that of a single cell (assuming the cells are similar). The orientation matters: connect the positive of one cell to the negative of the next so the voltages add in the same direction. Capacitors store energy in an electric field and aren’t formed by stacking energy sources. Inductors store energy in a magnetic field and aren’t created by series connections of cells. Resistors are passive components that dissipate energy; simply connecting cells doesn’t make a resistor. So the setup described corresponds to a battery.
