what is potential difference
Answers
Answer:
the difference of electrical potential between two points.
Explanation:
Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit.
**Measured in Volts: **Potential difference (p.d.) is measured in volts (V) and is also called voltage. The energy is transferred to the electrical components in a circuit when the charge carriers pass through them. We use a voltmeter to measure potential difference (or voltage).
Potential Difference formula:** V = I x R**
The potential difference (which is the same as voltage) is equal to the amount of current multiplied by the resistance. A potential difference of one Volt is equal to one Joule of energy being used by one Coulomb of charge when it flows between two points in a circuit.
Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points.
Formula
Ohm's law
V = IR
- V = voltage
- I = current
- R = resistance
