Electricity

What is the difference between the arrangement of bulbs in series and parallel circuits in a complete circuit?

• Arranged in one chain

• In series circuit, bulb is arranged in one chain while in parallel circuit arranged in several branches

• Arranged in several branches

Following are the components of electrical circuits...

• Dry cell

• Dynamo

• Switch

• Bulb

Which circuit has the brightest bulb?

• Parallel circuit

• Series circuit

State the difference in the brightness of the bulbs between series and parallel circuits

• Series circuit has brighter bulbs

• Parallel circuit has dimmer bulbs

• Parallel circuit has brighter bulbs

Why do the bulbs arranged in parallel circuit light brighter?

• In parallel circuit, electrical energy flows through each path is the same

• In series circuit, the bulbs doesn't share the same current

What happens when we increase the number of bulbs in a series circuit?

• Bulbs light brighter

• Bulbs becomes dimmer

How do we change the brightness of the bulbs in a parallel circuit?

• By increasing number of bulbs

• By removing wires

• By increasing number of dry cells

Does the brightness of bulb changes if the number of bulbs increases in parallel circuit?

• Yes

• No
