What Happens When a New Light Bulb is Added to a Series Circuit?

What happens to a series circuit consisting of three light bulbs if a new light bulb is added to the circuit?

Check all that are true:

  • resistance decreases
  • resistance increases
  • voltage decreases
  • voltage increases
  • current decreases

When a new light bulb is added to a series circuit consisting of three light bulbs, the following changes occur:

Voltage decreases: Adding another light bulb in series increases the total resistance in the circuit, causing a drop in voltage across each bulb.

Current decreases: As the total resistance in the circuit increases, the current flowing through the circuit decreases due to Ohm's Law (V = IR).

What are the effects of adding a new light bulb to a series circuit with three light bulbs? Adding a new light bulb to a series circuit with three light bulbs leads to a decrease in voltage and current in the circuit.
