How do you calculate ohms?

The calculation of ohms, which measures electrical resistance, is based on Ohm's Law. According to this law, resistance (R, measured in ohms) can be calculated by dividing the voltage (V, measured in volts) by the current (I, measured in amps). This means that resistance is directly proportional to the voltage applied and inversely proportional to the current flowing through a circuit. Therefore, the correct calculation is:

Ohms (R) = volts / amps.

Understanding this relationship is fundamental for anyone studying electrical concepts, as it lays the groundwork for working with circuits, troubleshooting electrical systems, and ensuring that components can handle the specified loads.

The other calculations presented do not correctly reflect the relationship outlined by Ohm's Law, leading to misunderstandings in electrical theory and practice.
