5.2 Series circuit and parallel circuit

What type of circuit has a single path for the electric current to flow?

• Parallel circuit

• Open circuit

• Combination circuit

• Series circuit

In which type of circuit can the electric current flow in more than one path?

• Series circuit

• Parallel circuit

• Combination circuit

• Closed circuit

How many paths for the electric current to flow are there in a series circuit?

• One

• Four

• Three

• Two

What type of circuit has bulbs arranged in several branches that are parallel to each other?

• Closed circuit

• Combination circuit

• Parallel circuit

• Series circuit

Which type of circuit has bulbs that are dimmer due to sharing the electric current?

• Parallel circuit

• Open circuit

• Combination circuit

• Series circuit

In a parallel circuit, why do the bulbs arranged in parallel light brighter?

• Less energy

• More paths for current

• More voltage

• More resistance

What is the symbol used to represent a closed switch in an electric circuit diagram?

• Line

• Triangle

• Square

• Circle

In a series circuit, what happens to the bulbs if one of the switches is opened?

• One bulb gets dimmer

• Both bulbs turn off

• One bulb gets brighter

• Both bulbs light up

Why does the other bulb still light up in a parallel circuit when one of the switches is opened?

• It is closer to the power source

• It has more energy

• It has less resistance

• Electric current can still flow through another path

What is the aim of the experiment to investigate the relationship between the conditions of switches and bulbs?

• To observe the effect of switches on bulbs

• To test different types of circuits

• To measure the resistance of the circuit

• To determine the brightness of the bulbs
