what is a volt- definition and explanation in breif
Basic introduction of what is a volt
In this article we will learn about what is a volt and its related terms. Volt is the standard unit of the potential difference or electromotive force (emf). Volt is denoted by (V). The amount of the force required to move 01 Amp of current thorough the wire or the metal is called 01 Volt. You will know that we can also called potential difference. One volt carries charge of one coloumb i.e (6.24*1018) through a wire having a resistance of one ohm in one second. The unit of voltage is volt named after the alessandro volta who is a great italian scientist and he was born in 1745 and died in the year 1827.

In mathematically, we can say that :-
V = I * R
V is the voltage in volt (V)
I is the current in ampere (A)
R is the resistance in ohms (Ω)
Example to find the value of the volt :-
- if 5A of current flows in the circuit and has a resistance of the 01 ohm. Then find the voltage
Solution = Here current= 05A, resistance= 01ohm voltage= ?
These are terms given in the question above
Applying the formula given above to find the volt.
V= 05*01 = 05
Here 05 V is the answer of this question.
similarly you can also find the value of the current and the resistance
The formula to find the current is I = V/R
and the formula to find the resistance is R = V/I
The standard voltage in india is 220v which is used in lightning loads and domestic sector mainly and 415V AC which is mainly used in the industrial sector. some countries uses 50 Hz or some uses 60 Hz of frequency. india is using 50Hz of frequency.
you can also read the related terms to what is a volt :-
- electrical resistance in a circuit
- static electricity defination and how it is produced
- capacitor symbol and working
Now, Lets understand the term what is a voltage or potential difference.
The force required to the flow of the current in a metal or wire from one end of the terminal to other end of the terminal is called the voltage or potential difference or emf( Electro Motive Force ). emf is generated by battery, cells etc. The instrument that is used to measure volt or potential differnce is called voltmeter. you can also measure potential difference with the help of the multimeter.
According to the ohm’s law when there is a high amount of voltage allows grater amount to the flow of current because the voltage is inversely proportional to the flow of the current through the wire for a given resistance.
There are two types of voltages :-
- AC voltage
- DC voltage
AC voltage- An AC voltages are the voltages that voltages changes its Direction after regular interval of the time. In ac voltages the voltage is also keep changing with respect to time. it made number of different waveforms like sinewave, triangle, squarewave etc. you can see these changes with digital voltmeter or digital multimeter.
DC voltage- Dc voltage are the voltage whose Direction constant with the respect to the time and its voltage also same with the respect to the time. in case of dc voltages they made a constant straight line on the screen.
Now lets understand that what is the direction if the voltage
The potential difference is basically a force that pushes the elctron from one end of the terminal to the other end of the terminal it flows from the negative terminal (-) to the positive (+) terminal.
