What is the formula for calculating current?

Current (I) is the rate of charge flow through a conductor, and its calculation formula is: I = V / R, where V is the voltage and R is the resistance. The specific steps are as follows: 1. Obtain the values ​​of voltage (V) and resistance (R); 2. Substitute V and R into the formula I = V / R; 3. Calculate the value of I in amperes (A).

Current calculation formula

Current is the rate of charge flow through a conductor. It is calculated using the following formula:

I = V / R

where:

• I is the current, The unit is Ampere (A)
• V is the voltage, the unit is Volt (V)
• R is the resistance, the unit is Ohm (Ω)

Explanation of the formula

Ohm's law states that the current flowing through a conductor is proportional to the voltage applied to it and inversely proportional to its resistance. Therefore, to calculate current we must know voltage and resistance.

How to use the formula

To use the formula to calculate current, simply plug the known voltage and resistance values ​​into the formula. For example, if the voltage is 12 volts and the resistance is 4 ohms, the current is:

I = 12 V / 4 Ω = 3 A

Thus, the flow through the conductor Current is 3 amps.
