Dimensional formula of Electric Current: Explained in Simple Terms

What is the Dimensional Formula of Electric Current?

Electric current is the rate at which electric charge flows through a conductor. It is measured in Amperes (A). The dimensional formula of electric current is [I] = [M]0[L]1[T]-1[I]1, where M stands for mass, L stands for length, T stands for time and I stands for electric current.

Why is the Dimensional Formula of Electric Current Important?

The dimensional formula for electric current is important because it describes the relationship between electric current, mass, length, and time. This formula allows us to understand the nature of electric current, and how it is related to other physical quantities.

How to Calculate Electric Current?

Electric current is calculated using Ohm’s law. The formula for calculating electric current is I = V/R, where V is the voltage, and R is the resistance. This formula allows us to calculate electric current based on the amount of voltage applied and the amount of resistance present.

Example:

Let’s say we have a voltage of 10 volts and a resistance of 5 ohms. We can calculate the electric current by plugging the values into the formula I = V/R. So, in this example, the electric current is 10/5 = 2 Amps.

Conclusion

The dimensional formula for electric current is an important concept that helps us understand the nature of electric current, and how it is related to other physical quantities. By understanding this formula, we can calculate electric current using Ohm’s law. This is an essential knowledge for anyone working in the field of electrical engineering.
