Answer:
Electric current does not flow through it. 5. In a circuit, the brightness of a bulb depends on: a) The number of batteries used (the greater the number of batteries, the brighter the bulb). ... As more batteries are added in series, more current is available and the bulbs become brighter.Jul 5, 2009
Explanation:
Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. In a series circuit, the voltage is equally distributed among all of the bulbs. Bulbs in parallel are brighter than bulbs in series. In a parallel circuit the voltage for each bulb is the same as the voltage in the circuit.
