You should really take a look at the article on Bridge circuits, which I pointed to in the earlier post. Once you understand how resistor bridge circuits work, it will not be much of a stretch to understand other components, such as capacitors.ShaddollDa9u said:
Potential difference across a capacitor, also known as voltage, is the difference in electric potential between the two plates of a capacitor. It is measured in volts (V) and is represented by the symbol "V" in equations.
The potential difference across a capacitor can be calculated by dividing the charge on the capacitor by its capacitance. This can be represented by the equation: V = Q/C, where V is the potential difference, Q is the charge, and C is the capacitance.
The potential difference across a capacitor is directly proportional to its capacitance. This means that as the capacitance increases, the potential difference across the capacitor also increases. This relationship is expressed by the equation: V ∝ 1/C.
The potential difference across a capacitor is directly related to the amount of energy it can store. As the potential difference increases, the energy stored in the capacitor also increases. This relationship is represented by the equation: E = 1/2 * CV^2, where E is the energy, C is the capacitance, and V is the potential difference.
Yes, potential difference across a capacitor can be negative. This occurs when the polarity of the capacitor is reversed or when it is connected in a circuit with a battery of opposite polarity. In these cases, the potential difference is still measured in volts, but with a negative sign to indicate the direction of the electric field.
