Electrical Circuit Troubleshooting: Series and Parallel Circuits

What is the definition of an electrical circuit?

• A closed loop that allows current to flow

• A device that stores electrical energy

• A material that resists the flow of electric current

• A source of electrical energy

Which of the following is a type of circuit where components are connected end-to-end?

• A) Series circuit

• B) Parallel circuit

• C) Open circuit

• D) Closed circuit

Identify the key components of an electrical circuit.

• Power source, conductors, loads

• Switches, batteries, wires

• Generators, transformers, resistors

• Capacitors, inductors, diodes

What happens to the current in a series circuit?

Evaluate responses using AI:

OFF

In a series circuit, the same current flows through all components. True or False?

• True

• False

How is voltage distributed in a series circuit?

Evaluate responses using AI:

OFF

If one component fails in a series circuit, what happens to the entire circuit?

• The entire circuit stops working

• Only the failed component stops working

• The circuit continues to work normally

• The circuit becomes a parallel circuit

Fill in the blank: Total resistance in a series circuit is calculated as R_{total} =

• R_{total} = R_1 + R_2 + R_3

• R_{total} = R_1 \times R_2 \times R_3

• R_{total} = R_1 - R_2 - R_3
