Basics of Electronics for Grade 6

What is a resistor used for in a circuit?

• To store electrical energy in a circuit.

• To increase current flow in a circuit.

• To convert electrical energy into heat.

• To limit current and control voltage in a circuit.

Name one common type of electronic component.

• Resistor

• Diode

• Capacitor

• Transistor

What does a circuit need to function properly?

• A single wire connection

• A power source, conductive pathways, and components.

• Only a resistor

• A battery without any connections

What is the difference between a series and a parallel circuit?

• A series circuit has multiple paths, while a parallel circuit has a single path.

• A series circuit has a single path for current, while a parallel circuit has multiple paths.

• Both series and parallel circuits have the same number of paths for current.

• A series circuit can operate without a power source, while a parallel circuit cannot.

In a series circuit, how does the current behave?

• The current varies at different points in a series circuit.

• The current is the same at all points in a series circuit.

• The current is zero in a series circuit.

• The current is higher at the beginning of the circuit.

What happens to the total resistance in a series circuit when more resistors are added?

• The total resistance increases.

• The total resistance decreases.

• The total resistance remains the same.

• The total resistance fluctuates randomly.

In a parallel circuit, how does the voltage behave across each component?

• The voltage is zero across all components.

• The voltage varies across each component.

• The voltage is different for each component.

• The voltage is the same across each component.

What is the purpose of a battery in a circuit?

• The purpose of a battery in a circuit is to supply electrical energy.

• To store data in a circuit.

• To increase the resistance in a circuit.

• To convert AC to DC in a circuit.

Can you name a device that uses a capacitor?

• Television

• Electric toothbrush

• Washing machine

• Camera flash

What happens to the current in a parallel circuit if one component fails?

• The total current remains the same regardless of the failure.

• The current continues to flow through other components; total current decreases.

• The current increases through the failed component.

• The current stops completely in the circuit.
