Due to inductance there is a spike in output voltage
A transient voltage is a time varying voltage value. Transient says that the voltage value changes, especially from a steady state, to a new value, then back again.
A transient, surge, spike, etc.
A practical opamp is designed to approach the characteristics of the ideal opamp as closely as possible. The open loop voltage gain of an ideal opamp is infinite, so while this is actually impossible to achieve practical opamps are built with as high an open loop voltage gain as possible.
An ideal voltage source has zero internal resistance so that the voltage stays constant with any load current. A practical voltage source should have less than 5% voltage drop at the rated load current.
Only if there's a 'load' across the voltage.
Surge voltage, voltage step, voltage spike

what are the practical uses of bec
Probably not. That is a very dangerous test. You create a voltage spike when unhooking the cable with the engine running. This spike could damage any of the computers on the car. The proper way to check an alternator is by it's output voltage when under load.Probably not. That is a very dangerous test.

Defective voltage regulator.
Any practical uses.
Ununtrium has not practical uses.
excessive voltage usually. can be caused by a voltage spike at the alternator, a computer sending too much voltage, or poor wiring
A resistor is connected in series with a practical voltage source in order to determine the current produced by the source.
When you close an inductive circuit, since an inductor resists a change in current, the initial reaction of the load is to look like a high resistance. As current builds, the resistance falls. With a theoretical source and inductor, current would eventually reach infinity, that is after infinite time, but practical sources and inductors will reach a plateau current. When you open an inductive circuit, again, since an inductor resists a change in current, the inductor attempts to maintain that current, but there is no conductivity for that current so, the inductor presents a high voltage spike in the reverse direction it was initially "charged" with. With a theoretical inductor, and theoretical infinite impedance, the voltage spike would be infinite. Again, practical inductors have a maximum voltage spike, but this spike can still be quite high, even thousands of volts, which can damage the circuit, so it is important to maintain a conduction path for the collapsing field, often a diode, or a resistor/capacitor filter.
