Potential difference charge and Energy - Equation

In summary, potential difference, also known as voltage, is the difference in electrical potential energy between two points in an electric circuit. It is measured in volts (V). Potential difference is calculated by dividing the change in electric potential energy by the amount of charge that moves through the circuit. It is directly proportional to the amount of charge, meaning that as potential difference increases, so does the amount of charge that moves through the circuit. Potential difference is also directly related to energy, as it is a measure of the work or energy required to move a unit of charge through a circuit. Lastly, potential difference is different from electric potential, as potential difference compares the energy at two points while electric potential measures the energy at one point.

Homework Statement


If the potential difference between a cloud and the ground is about 13MV , how much charge is transferred in a lightning bolt that releases 1.3GJ of energy?


Homework Equations





The Attempt at a Solution



1st can someone check my conversion - P.d=13*10^6V and E=13*10^9J
The main problem I have is that I don't know the equation relating E, P.V and q or if it exists... can someone please give me a hand... thanks

Related to Potential difference charge and Energy - Equation

1. What is potential difference?

Potential difference, also known as voltage, is the difference in electrical potential energy between two points in an electric circuit. It is measured in volts (V).

2. How is potential difference calculated?

Potential difference is calculated by dividing the change in electric potential energy (in joules) by the amount of charge (in coulombs) that moves through the circuit. This can be represented by the equation V = W/Q, where V is potential difference, W is work or energy, and Q is charge.

3. What is the relationship between potential difference and charge?

The potential difference is directly proportional to the amount of charge that moves through the circuit. This means that as potential difference increases, so does the amount of charge that moves through the circuit.

4. How does potential difference affect energy?

Potential difference is directly related to energy, as it is a measure of the work or energy required to move a unit of charge through a circuit. As potential difference increases, the amount of energy required to move the charge also increases.

5. What is the difference between potential difference and electric potential?

Potential difference is a measure of the difference in electric potential energy between two points, whereas electric potential is a measure of the electric potential energy at a single point in a circuit. In other words, potential difference compares the energy at two points, while electric potential measures the energy at one point.
