Media Image

This circuit is...?

open

parallel

closed

The cutest little circuit evah!

Answer explanation

The circuit is open because there is a break in the path, preventing current from flowing. In contrast, a closed circuit allows current to flow, while a parallel circuit has multiple paths for current. Thus, the correct answer is open.

A light bulb glows only in a

closed circuit

open circuit

open circuit if bulb is not fused

in both circuits

Answer explanation

A light bulb glows only in a closed circuit because it requires a complete path for electric current to flow. In an open circuit, the path is broken, preventing the flow of electricity and thus the bulb does not light up.

Media Image

A fifth-grade class constructed this circuit. Which of these objects most likely made the light glow when connected to points X and Y?

plastic straw

cotton string

aluminum foil

rubber eraser

Answer explanation

Aluminum foil is a good conductor of electricity, allowing current to flow and making the light glow. In contrast, a plastic straw, cotton string, and rubber eraser are insulators and would not complete the circuit.

Media Image

What kind of circuit is this?

Open Circuit

Closed Circuit

Answer explanation

A closed circuit allows current to flow continuously, completing the path for electricity. In contrast, an open circuit breaks this path, preventing current flow. Therefore, this circuit is a closed circuit.

Media Image

What kind of circuit is this?

Open Circuit

Closed Circuit

Answer explanation

An open circuit is one where the path for current flow is broken, preventing electricity from flowing. Since the correct answer is 'Open Circuit', it indicates that the circuit is incomplete.

Media Image

An incomplete circuit is shown.
To complete the circuit, a wire should be placed from:

Point D to Point C

Point B to Point C

Point A to Point D

Point B to Point D

Answer explanation

To complete the circuit, a wire must connect Point A to Point D, allowing current to flow through the circuit. This connection closes the loop, enabling the circuit to function properly.

MULTIPLE CHOICE QUESTION

45 sec • 1 pt

Media Image

What kind of circuit is this?

series

parallel

Answer explanation

The circuit is a series circuit because the components are connected end-to-end, allowing current to flow through each component sequentially. In a series circuit, the same current flows through all parts, confirming the correct choice.
