Question

What is potencial difference ?​

Answer 1

Answer:

Potential difference between any two points is defined as the amount of work done in moving a unit charge from one point to another.

Explanation:

• SI unit: volt
• In SI base units: kg⋅m2⋅s−3⋅A−1
• Dimension: M L2 T−3 I−1
• Derivations from other quantities: Voltage = Energy / charge

Voltage

Formula

Ohm's law

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: V = IR$

$V = voltage$

$I = current$

$R = resistance$

Answer 2

Explanation:

Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit. ... 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
