Electricity Unit Review (LT's 1-5 only)

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.

Front

What is the relationship between current (I) and resistance (R) according to Ohm's Law?

Back

According to Ohm's Law, current (I) and resistance (R) are inversely proportional.

What is the relationship between current (I) and voltage (V) according to Ohm's Law?

Back

According to Ohm's Law, current (I) and voltage (V) are directly proportional.

Front

What is voltage?

Back

Voltage, also known as electric potential difference, is the 'pressure' that pushes electric charges through a circuit. It is measured in volts (V).

Front

What provides electrons flowing through a circuit?

Back

Electrons flowing through a circuit are provided by the wires.

Front

What is the law of charge conservation?

Back

The law of charge conservation states that the total charge in an isolated system remains constant. Charge can neither be created nor destroyed, only transferred.

Front

How do objects become charged according to the law of charge conservation?

Back

Objects become charged through the transfer of electrons between objects.

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, measured in ohms (Ω).

Front

What is an electrical load?

Back

An electrical load is any device or component that consumes electrical energy in a circuit, such as a light bulb or resistor.

Front

What is the unit of measurement for electric current?

Back

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