voltage
Voltage is not an absolute figure. Voltage Difference is the exact term. So, the voltage difference between the two wires in the 220 V circuit will be 220V.
Electromotive force is an old term for voltage.
Voltage.The correct term for the amount of energy per unit of charge is potential difference.Energy = Charge * VoltageSimple rearranging gives: Voltage = Energy / ChargeTherefore a volt can be defined as a "joule per coulomb".
Alessandro Volta. The term volt.voltage was named after him

'Nominal' means 'named'. So a 'nominal' voltage is the named voltage of a system. For example, when we talk about a 120-V or 240-V system, we are describing their nominal values, not their actual values which can change from moment to moment.
Only if there's a 'load' across the voltage.
It means electricity power
The terms potential and voltage are somewhat interchangeable when used to indicate electric pressure. The proper term is voltage, or volts, which is actually a combined term that means joules per coulomb or, in simpler terms, energy per charge.
Yes. Another term for voltage is EMF, electro-motive-force.
voltage
Nominal voltage is the 'named' voltage -for example, the nominal supply voltage in the UK is 230 V. But this is not necessarily the actual voltage at a particular time. A nominal voltage is normally expressed together with the percentage by which it is permitted to vary from that stated value. For example, in the UK, the nominal voltage is expressed as: 230 V +10% / -6% --in other words it is allowed to vary between 216.2 and 253 V.The term, operating voltage, isn't actually defined anywhere, but is usually taken to mean the actual voltage supplied to a device at any particular instant, and this should always fall within the allowable range of the supply system's specified nominal voltage. The operating voltage can be found simply by measuring it with a voltmeter.
