Electrical Circuits

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which the components are connected end-to-end, so that the current flows through each component in turn. If one component fails, the entire circuit is broken.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where the components are connected across common points or junctions, providing multiple pathways for the current. If one component fails, the others can still operate.

What is the role of a battery in a circuit?

Back

A battery serves as the power source in a circuit, providing the necessary voltage to drive the current through the circuit.

Front

What happens in a parallel circuit if one light bulb burns out?

Back

In a parallel circuit, if one light bulb burns out, the other bulbs can still light up because they have separate pathways for the current.

Front

What is an incomplete circuit?

Back

An incomplete circuit is a circuit that does not have a complete path for current to flow, preventing the operation of electrical devices.

Front

What is the function of a switch in a circuit?

Back

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

Front

Define electrical current.

Back

Electrical current is the flow of electric charge, typically measured in amperes (A). It represents the movement of electrons through a conductor.

Front

What is voltage?

Back

Voltage, measured in volts (V), is the electrical potential difference between two points in a circuit. It drives the current through the circuit.

Front

What is resistance in an electrical circuit?

Back

Resistance is the opposition to the flow of electric current, measured in ohms (Ω). It determines how much current will flow for a given voltage.

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). It is expressed as V = I × R.
