Question 1 of 3

A lamp is connected to a circuit that uses two AA cells (each 1.5 V). If the number of cells is increased to four AA cells connected in series, what will happen to the brightness of the lamp?

Question 2 of 3

A lamp is connected to a circuit that uses AA cells. When the circuit has two cells (total 3 V), the lamp glows faintly. If the number of cells is increased to four cells (total 6 V) while everything else stays the same, what will happen to the lamp’s brightness?

Question 3 of 3

A simple circuit has a lamp connected to a battery pack. When the pack contains 2 cells, the lamp glows dimly. If the number of cells in the pack is increased to 4 cells (same type of cells), what will happen to the lamp’s brightness?
