Ohm's Law relates voltage (V), current (I), and resistance (R) in a circuit and is expressed as:
V = I * R
However, Ohm's Law does not directly relate voltage and capacitance. Capacitance (C) is a property of capacitors and represents their ability to store electric charge. The relationship between voltage and capacitance in a capacitor-based circuit is defined by the formula:
Q = C * V
Where:
Q is the charge stored in the capacitor,
C is the capacitance of the capacitor (measured in Farads, F), and
V is the voltage across the capacitor.
In words, the charge stored in a capacitor is directly proportional to the capacitance and the voltage applied across it. When a voltage is applied to a capacitor, it accumulates charge until it reaches its capacity (determined by the capacitance). The relationship between voltage and capacitance is essential in understanding the behavior of capacitors in electronic circuits.
