Ohm’s Law Calculator – Formula, Free Online Tools, Mobile Apps & FAQs for South Africans
What Is a Ohm’s Law Calculator?
An Ohm’s Law Calculator is a useful tool for calculating the relationship between voltage, current, and resistance in an electrical circuit. In South Africa, this calculator can help individuals, students, and professionals understand the basics of electricity and make informed decisions when dealing with electrical systems. For example, it can be used to determine the correct resistor value in an LED circuit or calculate the power dissipated in a specific component.
How to Calculate Ohm’s Law Manually
Ohm’s Law is expressed by the formula: V = I x R, where V is voltage, I is current, and R is resistance. To calculate the voltage, multiply the current by the resistance. For example, if the current is 2A and the resistance is 5Ω, the voltage would be 10V.
Let’s say you have a circuit in South Africa with a current of 3A and a resistance of 8Ω. To find the voltage, you would simply multiply 3A by 8Ω, resulting in a voltage of 24V.
