Question

Which of these statements is true about series and parallel circuits?

a) Light bulbs in series will shine more brightly than light bulbs in parallel

b) The current through each of the light bulbs in parallel is about half of the total current in the circuit

c) The voltage across each of the light bulbs in parallel is about half of the total voltage in the circuit

Answer 1

Explanation:

In series, both bulbs have the same current flowing through them. The bulb with the higher resistance will have a greater voltage drop across it and therefore have a higher power dissipation and brightness. In parallel, both bulbs have the same voltage across them.
