# Finding potential difference(electric circuit)

• Jabababa
In summary, 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 and is responsible for the flow of electric current. It can be calculated by dividing the amount of work done by the electric charge in moving from one point to another. The main factors that affect potential difference are the voltage of the power source and the resistance of the circuit components. Higher voltage results in a higher potential difference, while higher resistance results in a lower potential difference. The potential difference is responsible for the flow of electric current in a circuit, with a higher potential difference resulting in a higher current and a lower potential difference resulting in a lower current. Potential difference is commonly measured in volts or

The steps are fine, and the values look reasonable. I would use less decimal places, however.

## 1. What is potential difference in an electric circuit?

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 and is responsible for the flow of electric current.

## 2. How do you calculate potential difference?

Potential difference can be calculated by dividing the amount of work done by the electric charge in moving from one point to another, also known as voltage. The formula is V = W/Q, where V is potential difference (in volts), W is work done (in joules), and Q is electric charge (in coulombs).

## 3. What factors affect potential difference in a circuit?

The main factors that affect potential difference in a circuit are the voltage of the power source and the resistance of the circuit components. Higher voltage will result in a higher potential difference, while higher resistance will result in a lower potential difference.

## 4. How does potential difference affect the flow of electric current?

The potential difference is responsible for the flow of electric current in a circuit. The greater the potential difference, the greater the force pushing the electric charges through the circuit, resulting in a higher current. In contrast, a lower potential difference will result in a lower current.

## 5. What are some common units for measuring potential difference?

Potential difference is commonly measured in volts (V) or millivolts (mV). Other units that may be used include kilovolts (kV) and microvolts (µV). In some cases, potential difference may also be measured in electron volts (eV) in the field of particle physics.
