Electric Circuits

Front

What is a battery in an electric circuit?

Back

A battery is a device that stores chemical energy and converts it into electrical energy to provide power to a circuit.

What does the symbol for a lamp represent in an electric circuit?

Back

The symbol for a lamp represents a device that converts electrical energy into light energy.

Front

What is a series circuit?

Back

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

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit in which components are connected across common points or junctions, allowing multiple paths for current to flow.

Front

What happens if one component fails in a series circuit?

Back

If one component fails in a series circuit, the entire circuit is broken and all components stop working.

Front

What is one advantage of using a parallel circuit?

Back

If one component fails in a parallel circuit, the other components continue to function normally.

Front

What is the role of a resistor in an electric circuit?

Back

A resistor is a component that limits the flow of electric current in a circuit, providing resistance.

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.

Front

What is the unit of electric current?

Back

The unit of electric current is the Ampere (A).

Front

What is the unit of voltage?

Back

The unit of voltage is the Volt (V).
