Explanation

• Volt (V) is the SI unit of potential difference (voltage).
• Potential difference is the electrical force that causes current to flow through a conductor.
• It is measured using a voltmeter.
• The SI unit is named after Alessandro Volta.

Additional information:

• Electric Current: Ampere (A)
• Resistance: Ohm (Ω)
• Power: Watt (W)
• Charge: Coulomb (C)

Explanation

• Weber (Wb) is the SI unit of magnetic flux.
• One Weber is equal to one volt-second (V·s).
• A magnetic flux density of 1 Weber per square metre (1 Wb/m²) is equal to 1 Tesla (T).
• Magnetic flux measures the total magnetic field passing through a surface.
