By approaching a light bulb, does the brightness increase or stays the same?

Sagot :

Answer:

  • 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.
  • No the bulbs won't glow with the same brightness in both circuits. The bulb in parallel circuit will glow brighter than when connected in series.
