Measured in Ohms (Ω), it quantifies the opposition to electric current.

Electric current

Measured in Amperes (A), it is the flow of electric charge.

Density

Measured in kilograms per cubic metre (kg/m³), it is the mass per unit volume of a substance.

Power

Measured in Watts (W), it indicates the rate at which energy is transferred or converted.

Celsius temperature

Measured in degrees Celsius (°C), it is a scale used for measuring temperature.

Velocity

Measured in metres per second (m/s), it indicates the speed of an object in a specific direction.

Capacitance

Measured in Farads (F), it quantifies the ability of a system to store electric charge.
