Electricity and Circuits

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

• The current stops flowing completely.

• The current can still flow through other paths, so the remaining components continue to function.

• The current increases in the remaining components.

• The current is divided equally among all components.

What is the effect of resistance in a circuit?

• Resistance increases the flow of electric current.

• Resistance has no effect on electric current.

• Resistance opposes the flow of electric current, affecting the amount of current that can flow.

• Resistance only affects voltage in a circuit.

What type of circuit allows multiple paths for electricity to flow?

• Series circuit

• Parallel circuit

• Open circuit

• Short circuit

What is the role of a battery in a circuit?

• A battery stores electrical energy for later use.

• A battery provides the electrical energy needed to power the circuit.

• A battery acts as a resistor to limit current flow.

• A battery converts electrical energy into mechanical energy.

What is the purpose of a light bulb in a circuit?

• A light bulb converts electrical energy into light energy.

• A light bulb stores electrical energy for later use.

• A light bulb increases the voltage in a circuit.

• A light bulb acts as a resistor to limit current.

What is the primary reason electrical wiring is made from copper?

• Copper is abundant and inexpensive.

• Copper conducts electricity.

• Copper is lightweight and flexible.

• Copper is resistant to corrosion.

What is the function of conductors in a circuit?

• Conductors allow electricity to flow through them easily.

• Conductors block the flow of electricity.

• Conductors store electrical energy for later use.

• Conductors convert electrical energy into heat.

What happens when a switch in a circuit is closed?

• Electricity can flow in a complete path.

• Electricity is blocked from flowing.

• The circuit becomes open.

• Only some devices in the circuit receive power.

What material can be used to create a simple circuit that makes a light glow?

• Copper wire

• Aluminum foil

• Plastic

• Wood

What is the effect of an open switch in a circuit with a light bulb?

• The light bulb will not light because the switch is open.

• The light bulb will glow dimly.

• The light bulb will flicker intermittently.

• The light bulb will light up brightly.
