Electric Current & Ohm's Law P1

Front

What is electric current?

Back

Electric current is the continuous flow of electric charges through a material.

Front

What is the unit for measuring electric current?

Back

The unit for measuring electric current is the ampere.

Front

What are insulators?

Back

Insulators are materials such as rubber that do not allow charges to flow.

Front

What is the energy transformation in a generator?

Back

In a generator, the energy transformation is EMR (Electromagnetic Radiation) to electric charges (e-).

Front

What is the energy transformation in a motor?

Back

In a motor, the energy transformation is electric charges (e-) to mechanical energy (M).

Front

What is resistance in an electric circuit?

Back

Resistance is a measure of the opposition to the flow of electric current in a material.

Front

What is voltage?

Back

Voltage is the electric potential difference between two points in a circuit.

Front

What is a conductor?

Back

A conductor is a material that allows electric charges to flow easily.

Front

What is static discharge?

Back

Static discharge is the sudden flow of electricity between two electrically charged objects.

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).
