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 can be expressed as V = I × R.

Front

What is resistance in an electrical circuit?

Back

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

Front

What surrounds a wire when electric current flows through it?

Back

A magnetic field surrounds the wire when electric current flows through it.

Front

What happens in a series circuit if one component fails?

Back

If one component (like a light bulb) in a series circuit fails, the entire circuit is broken and all components stop working.

Front

What is a conductor?

Back

A conductor is a material that allows electric current 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 current. Examples include rubber, glass, and plastic.

Front

What are magnetic field lines?

Back

Magnetic field lines are visual representations of the magnetic field around a magnet. They show the direction and strength of the magnetic field.

Front

What is the unit of electric current?

Back

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

Front

What is the relationship between voltage, current, and resistance?

Back

The relationship is defined by Ohm's Law: V = I × R, where V is voltage, I is current, and R is resistance.

Front

What is the effect of increasing resistance in a circuit?

Back

Increasing resistance in a circuit decreases the current flow, assuming the voltage remains constant.
