SECOND SUMMATIVE TEST

What is an electric circuit?

• A device that stores electrical energy

• A material that resists electricity

• A path through which electrons can flow

• A source of electrical energy

What is the function of a battery in a circuit?

• To connect wires together

• To increase resistance

• To provide electrical energy

• To store electricity permanently

What happens to the voltage in a parallel circuit?

• It increases with each component

• It is divided among components

• It remains constant throughout the circuit

• It stops at every component

In a parallel circuit, what remains the same across all components

• current

• power

• resistance

• voltage

What happens if one component fails in a parallel circuit?

• The entire circuit stops working

• The failed component repairs itself

• The remaining components continue functioning

• The voltage decreases in all components

Why are parallel circuits used in home wiring?

• To create a single path for current

• To ensure appliances work independently

• To increase power consumption

• To reduce the number of connections

What is a key characteristic of a series circuit?

• A single path for current

• Components operate independently

• Multiple paths for current

• The same voltage across all components

What is one advantage of a parallel circuit over a series circuit?

• Equal current distribution

• Higher resistance across components

• Independent operation of components

• Lower power consumption

Which of the following is an example of a series circuit?

• flashlight

• home wiring system

• modern LED Christmas lights

• streetlights

What happens to the brightness of bulbs in a series circuit when more bulbs are added?

• It decreases

• It increases

• It remains the same

• It turns off completely
