In an AC circuit, how does the current behave?

It reverses direction periodically

What is the relationship between the number of protons and electrons in an electrically neutral atom?

The number of protons is equal to the number of electrons

The number of protons is more than electrons

The number of electrons is more than protons

There is no specific relationship

How is the single electron in the outer orbit of the copper atom described?

Completely detached from the atom

What happens when a material is connected across a battery?

The positive plate attracts electrons, while the negative plate repels them.

The positive plate repels electrons, and the negative plate attracts them.

What does the battery provide in an electric circuit?

A source of electromotive force (EMF)

According to the electron theory, how is the direction of conventional current related to electron flow?

It flows in the opposite direction to electron flow.

It flows in the same direction as electron flow.

It is perpendicular to electron flow.

It is unrelated to electron flow.

What is voltage in electrical terms?

Voltage is electrical pressure and creates current flow

Voltage is the resistance to current flow

Voltage is the rate of flow of charge

Voltage is a type of electrical insulation

What creates a flow in the direction of lower pressure in electrical terms?

A difference in pressure between two points

A similarity in pressure between two points

A constant pressure at one point

What is the relationship between resistance and current flow according to the image?

The higher the resistance, the less current that will flow

The higher the resistance, the more current that will flow

The lower the resistance, the more current that will flow

The resistance has no impact on the current flow

Refer to the diagram above, which triangle correctly represents the formula to find current (I)?

To find current: I at the top, V and R at the bottom

To find voltage: V at the top, I and R at the bottom

To find voltage: I at the top, V and R at the bottom

To find current: R at the top, V and I at the bottom

What is an electrical circuit?

A path or line through which an electrical current flows

A device that stores electrical energy

A tool used to measure electrical current

What does a closed circuit allow?

It allows electrical current to flow

It prevents electrical current from flowing

What is the consequence of an open circuit?

It does not allow electrical current to flow

It allows electrical current to flow more efficiently

It allows electrical current to flow without interruption

It stores electrical current for later use

What are the main components of an electric circuit as mentioned in the learning material?

Conductors, load, power source, protective device, and a switch

Conductors, resistors, capacitors, inductors, and a power source

Wires, batteries, resistors, capacitors, and LEDs

Transistors, diodes, wires, a switch, and a battery

What is the function of conductors in an electric circuit?

To make the path through which electricity flows

To regulate the flow of electricity

To convert electrical energy into light

What is the role of one piece of the wire in an electric circuit?

It connects the load back to the power source

It serves as a switch to turn the circuit on and off

It converts the electrical energy into mechanical energy

What is the function of a switch in an electrical circuit?

To interrupt the flow of electricity

To increase the flow of electricity

To measure the flow of electricity

What happens when the switch in the circuit is closed?

The circuit is completed and electricity flows.

The circuit is interrupted and electricity does not flow.

The circuit remains unchanged and electricity does not flow.

The circuit overheats and electricity flow stops.

What does conventional current assume in terms of the direction of current flow?

Current flows from the negative terminal to the positive terminal through the circuit.

Current flows out of the positive terminal, through the circuit, and into the negative terminal of the source.

Current does not flow through the circuit; it only flows within the source.

Current flows in a random direction, independent of the terminals.
