Grade 7 - Checkpoint 1 - Term 2

one of these is not an electric circuit components:

• Battery

• wires

• bulb

• iron

This shape represents :

• Switch

• fixed resistor

• variable resistor

• battery

the open switch means it's

• on (activated )

• off ( deactivated)

why do we need the resistor?

• to turn the light on or off

• They are used to limit the current flowing through an electric circuit

• to give power and electricity to the circuit

What we call this item in the electrical circuit?

• Breadboard

• Switch

• resistor

• battery

the terminal to which the current flows into the circuit

• breadboard

• anode

• cathode

• signal

the terminal from which the current leaves a circuit

• breadboard

• anode

• cathode

resistors are used when the value of the resistor required in a circuit is unknown or might be changed.

• Fixed resistor

• Variable resistor

An electronic components store energy and are used in most electronic circuits.

• Capacitors

• Potentiometer

• Resistors

You no longer need to walk to the grocery store, you can send a message instead and have items delivered.

• True

• False
