Current flow in a circuit can be calculated by which formula?

The formula for calculating current flow in a circuit is derived from Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). This relationship implies that when you want to find the current flowing through a circuit, you take the voltage across the components and divide it by the resistance offered by those components. Therefore, the formula clearly shows that dividing volts by ohms gives you the current in amperes.

This understanding is fundamental in electrical circuitry, as it helps technicians and engineers determine how much current is flowing for a given voltage and resistance, which is crucial for troubleshooting and designing electrical systems.
