Answer:

Current, Voltage, Resistance

Voltage

Symbol: V

Definition: Voltage is the amount of potential energy between two points on a circuit.

Units of Measurement: volts ( )

Unit (Abbreviation): v

Instrument Used to measure: voltmeter

Current

Symbol: I

Definition: The amount of charge flowing through the circuit over a period of time.

Units of Measurement: ampere ()

Unit (Abbreviation): a

Instrument Used to measure: ammeter

Resistance

Symbol: R

Definition: It is the opposition to the flow of current in an electric circuit.

Units of Measurement: ohms

Unit (Abbreviation): symbol for omega

Instrument Used to measure: ohmmeter

Explanation

One of the most important and basic laws of electrical circuits is Ohm's law. It describes the relationship between current, voltage, and resistance. According to this law, the current passing through a conductor is proportional to the voltage over the resistance. Mathematically, this can be expressed in the following equation:

I =

where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms.

Ohm's law describes how the current flows through resistance when voltage is applied. This can be compared to water flowing through a pipe. The amount of water flowing is current, the water pressure is the voltage, and the size of the pipe is the resistance. More water will flow (current) if more pressure is applied (voltage) and bigger pipe (lower resistance).
