Hint: An electrical quantity is quantities which supports the flow of electricity. The electrical quantities are charge, current, voltage, power and energy.Electric current is a scalar quantity. Any physical quantity is termed as a vector quantity when the quantity has magnitude and direction. But there are other factors that determine the quantity as vector or scalar quantity.
Complete answer:
The basic three electrical quantities are:
-Voltage
-Electric current
-Resistance
Voltage: The voltage, the electric potential difference, the electric pressure or the electric tension of the charge is measured in the volts. It is well-defined as the work done per unit of charge to move the charge between the two points. One volt can be well-defined as the energy consumption of one joule per electric charge of the one coulomb.
Electric current: Current can be defined as the rate at which charge crosses a point on the circuit. Current is measured in terms of coulombs.
Resistance: The resistance can be defined as the ratio of potential difference (V) and the current (I). That is . The physical property of the conductor which resists the flow of current and the electrons is known as the resistance and it is used to decrease the flow of current and voltages. The resistance is symbolized by and measured in ohm. (SI unit)
Note: In electronic circuits, the resistors are used to decrease the flow of current flow, to regulate the signal levels, to split voltages and terminate the transmission lines whereas; the property of the resistivity is used to quality check and comparing different materials on the root of the ability to conduct electricity.
