Electrical Calculator – Formula, Free Online Tools, Mobile Apps & FAQs for South Africans
What Is an Electrical Calculator?
An electrical calculator is a tool used to perform various calculations related to electrical circuits, components, and parameters. In South Africa, this tool is essential for electricians, engineers, students, and anyone dealing with electrical systems. Some common examples include calculating voltage, current, resistance, power, and energy consumption.
How to Calculate Electrical Values Manually
The most fundamental formula in electrical calculations is Ohm’s Law, which states that V = I x R, where V is voltage, I is current, and R is resistance. To calculate power, you can use the formula P = V x I. Energy consumption can be calculated by multiplying power by time, E = P x t.
For example, if you have a circuit in South Africa with a voltage of 220V and a current of 5A, you can calculate the power as follows: P = 220V x 5A = 1100W.
