Electrical circuits part two

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where 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 components are connected across common points or junctions, providing multiple paths for the current to flow. If one component fails, the current can still flow through other paths.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily. Examples include rubber, glass, and plastic.

Front

What factors affect the resistance of a material?

Back

The resistance of a material is affected by its thickness, temperature, and length. Thicker wires have less resistance, higher temperatures increase resistance, and longer wires have more resistance.

Front

What is resistance in an electrical circuit?

Back

Resistance is a measure of the opposition to the flow of electric current in a circuit. It is measured in ohms (Ω).

Front

What happens to the total resistance in a series circuit when more resistors are added?

Back

In a series circuit, the total resistance increases as more resistors are added.

Front

What happens to the total resistance in a parallel circuit when more resistors are added?

Back

In a parallel circuit, the total resistance decreases as more resistors are added.

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 a closed circuit?

Back

A closed circuit is a complete electrical circuit through which current can flow. It has no breaks or interruptions.
