The potential difference between two plates is measured using a voltmeter, which is connected in parallel to the plates. The voltmeter measures the voltage or potential difference in volts (V).
The unit of potential difference is volts (V). This is a derived unit in the International System of Units (SI) and is equivalent to one joule per coulomb (J/C).
Potential difference, also known as voltage, is directly proportional to the number of electrons that are transferred between two points. This means that the higher the potential difference, the greater the number of electrons transferred.
Yes, potential difference can be negative. This occurs when the direction of electron flow is opposite to the direction of conventional current flow. In such cases, the potential difference is denoted with a negative sign.
The formula for calculating electron transfer based on potential difference is Q = CV, where Q is the charge transferred in coulombs, C is the capacitance in farads, and V is the potential difference in volts. This formula is known as the charge-voltage relationship in electrical circuits.
