Electric Current

Front

What is electric current?

Back

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

Front

What is the unit of electric current?

Back

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

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 can be expressed as V = I × R.

What happens to current in a series circuit?

Back

In a series circuit, the current remains the same throughout all components.

Front

What happens to voltage in a series circuit?

Back

In a series circuit, the total voltage is the sum of the voltages across each component.

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 paths for current to flow.

Front

What happens to resistance in a parallel circuit when more branches are added?

Back

When more branches are added to a parallel circuit, the total resistance decreases.

Front

What is a resistor?

Back

A resistor is a component that resists the flow of electric current, creating a voltage drop.

Front

What is a conductor?

Back

A conductor is a material that allows electrons to flow easily, facilitating the movement of electric current.

Front

What is an insulator?

Back

An insulator is a material that does not allow electrons to flow easily, preventing the movement of electric current.
