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 in which the components are connected across common points or junctions, providing multiple paths for the current. If one component fails, the others can still operate.

What is a Conductor?

Back

A conductor is a material that allows electric charges to flow through it easily. Examples include metals like copper and silver.

Front

What is an Insulator?

Back

An insulator is a material that resists the flow of electric charges. Examples include rubber, glass, and plastic.

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

Back

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

Front

What happens to light bulbs in a series circuit if one burns out?

Back

In a series circuit, if one light bulb burns out, the entire circuit is broken and all the bulbs go out.

Front

What do electric charges that are alike do to each other?

Back

Electric charges that are alike repel (move away) from each other.

Front

What do electric charges that are opposite do to each other?

Back

Electric charges that are opposite attract each other.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push the electric charges through the circuit.

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. It is expressed as V = I × R.
