Ohm's Law is a fundamental principle in electrical circuits, and it relates three essential electrical quantities: voltage (V), current (I), and resistance (R). The equation for Ohm's Law is:
V = I * R
Where:
V = Voltage (measured in volts, V)
I = Current (measured in amperes, A)
R = Resistance (measured in ohms, Ω)
This equation states that the voltage across a conductor (such as a resistor) is equal to the product of the current flowing through it and the resistance of the conductor. It provides a simple way to calculate any of these values if the other two are known.
