mr newtein said:why is potential difference same in parallel and gets divided in series,also what does it means this much pd is apllied by cell.pleaseeeeeee explain working of all this,i am getting frustrated as i am not able to understand
Potential difference, also known as voltage, is the difference in electrical potential between two points in a circuit. It is measured in volts and represents the amount of energy that is required to move an electric charge from one point to another.
In a series circuit, the potential difference is divided among the components, meaning that the total potential difference across the circuit is equal to the sum of the potential differences across each component. In a parallel circuit, the potential difference is the same across each component, as the components are connected in parallel to the same voltage source.
In a series circuit, the potential difference can be higher than the potential difference of a single component, as it is divided among multiple components. In a parallel circuit, the potential difference is the same across each component, so it cannot be higher than the potential difference of a single component.
Potential difference is directly proportional to the flow of current in a circuit. This means that as the potential difference increases, the current will also increase, and as the potential difference decreases, the current will also decrease.
Yes, potential difference can be negative. This indicates that the direction of the electric current is opposite to the direction of the voltage source. In a circuit, this can occur when the current is flowing in the opposite direction than expected.
