Question

A circuit with _________________ will glow the brightest (considering all the bulbs and cells to be identical).

• A. one bulb and one cell
• B. one bulb and two cells in series
• C. two bulbs and one cell
• D. three bulbs and one cell

Answer 1

The correct option is B one bulb and two cells in series

The chemical energy stored in two cells is more than that in one, which is converted to electrical energy. When the cells are connected in series, it results in more brightness of the bulb. So, the bulb in the circuit that has one bulb and two cells in the series will glow the brightest.
