Ohm's Law is simply called "Ohm's Law," named after the German physicist
Georg Simon Ohm, who first formulated it. It describes the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit.
In its basic form, Ohm's Law is expressed as:
\[
V = I \times R
\]
Where:
- \( V \) is the voltage (in volts),
- \( I \) is the current (in amperes),
- \( R \) is the resistance (in ohms).
So, Ohm's Law helps us understand how electrical circuits behave and allows us to calculate any one of the three quantities (voltage, current, resistance) if the other two are known.
