What is Volt?
Volts is a measurement unit used in an electrical system to measure electrical potential difference or voltage between two points in an electrical circuit. It is named to honor Italian physicist Alessandro Volta, who invented the first electrical battery. Volts are measured using a device called a voltmeter, which is connected to the circuit and reads the voltage between two points. The unit of measurement for volts is the volt, which is denoted as “V”.
In simple terms, volts are a way of measuring how much electrical force is pushing electric charges through a circuit. Think of it like water flowing through a tube– the voltage is like the pressure that pushes the water through the tube. In an electrical circuit, the voltage is what makes the electric current flow.
Volts Formula:
Volts = Amperes x Resistance
This formula knows as Ohm’s Law.
Example: A current of 2 amperes (A) flowing through it and a resistor with a resistance of 5 ohms (Ω). We want to calculate the voltage (V) across the resistor.
Solution: Using Ohm’s law, we can rearrange the formula V = IR to solve for V, which gives:
V = IR
Substituting the given values, we get:
V = 2A x 5Ω
V = 10V
Difference Between Watts And Volts
Unit of measurement for electrical potential difference or voltage Watts and volts are the two different units of measurement that are commonly used in physics in the electricity field. Watts and Volts both are necessary for understanding the working of electric circuits and electric devices. Watts is the unit of power, while volts are the unit of electrical potential difference between two places in the circuit. Watt helps in understanding the quantity of energy being generated or consumed whereas volt helps in understanding the difference in the electrical potential of two places.
