Series and parallel circuits – What happens next?

The video explains the impact of adding more light bulbs to an electrical circuit. As more components are added, resistance increases, leading to a decrease in the brightness of the bulbs. This concept is crucial for understanding how circuits function and the role of resistance in electrical systems.

What is the immediate action taken in the circuit?

• Two more light bulbs are added.

• A switch is turned off.

• The circuit is disconnected.

• A resistor is removed.

What happens when more components are added to a circuit?

• There is less opposition to electricity flow.

• The opposition to electricity flow increases.

• The circuit becomes more efficient.

• The circuit starts to overheat.

How does adding more components affect the brightness of the bulbs?

• The bulbs shine more brightly.

• The bulbs shine less brightly.

• The bulbs flicker.

• The bulbs remain unchanged.

What is the term used to describe the opposition to the flow of electricity?

• Resistance

• Voltage

• Capacitance

• Current

What is the effect of resistance on the circuit?

• It increases the current.

• It decreases the brightness of the bulbs.

• It makes the circuit faster.

• It reduces the voltage.
