What is the role of a switch in a circuit?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of electricity.

Front

What is a power source in a circuit?

Back

A power source provides the electrical energy needed for the circuit to function, such as a battery or power outlet.

What is a closed path in a circuit?

Back

A closed path is a complete loop that allows electricity to flow uninterrupted through the circuit.

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected end-to-end, so the same current flows through all components. In a parallel circuit, components are connected across common points, allowing multiple paths for current.

What is the function of a resistor in a circuit?

Back

A resistor limits the flow of electric current in a circuit, protecting components from excessive current.

Front

What is the purpose of a capacitor in a circuit?

Back

A capacitor stores electrical energy temporarily and can release it when needed, helping to smooth out voltage fluctuations.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor, expressed as V = I * R.

What is the function of a diode in a circuit?

Back

A diode allows current to flow in one direction only, acting as a one-way valve for electricity.

What is the significance of circuit diagrams?

Back

Circuit diagrams provide a visual representation of an electrical circuit, showing how components are connected and the flow of electricity.
