How does a battery creates a potential difference and what is the intuative way to look at potential difference when studying capacitance
Potential difference, also known as voltage, is the difference in electric potential energy between two points in an electric circuit. It is measured in volts (V) and determines the amount of work needed to move a unit of charge from one point to another.
A battery is a device that converts chemical energy into electrical energy. When a battery is connected to a circuit, it creates a potential difference between its positive and negative terminals, which causes the flow of electrons and powers the circuit.
The unit of potential difference is the volt (V), named after Italian physicist Alessandro Volta. One volt is equal to one joule of energy per coulomb of charge.
According to Ohm's Law, the current (I) flowing through a conductor is directly proportional to the potential difference (V) and inversely proportional to the resistance (R) of the conductor. This means that as the potential difference increases, the current also increases.
Yes, potential difference can be negative. A negative potential difference means that the electric potential at the starting point is higher than the ending point. This can occur when the direction of flow of electrons is opposite to the direction of conventional current flow.
