Only if there's a 'load' across the voltage.
voltage
It means electricity power
Blackout, Brownout, Spike, Surge and Noise.
Yes. Another term for voltage is EMF, electro-motive-force.
change in load voltage or output voltage changes in load current
Another term for power relations is "power dynamics." This term refers to the ways in which power is maintained, exerted, and negotiated in various social contexts.
the formular notation for voltage drop is Ed Another possible term is "IR loss" meaning the current (I) x resistance (R) loss on the wire part of a circuit
A brown out.
Staying power is another term that can be used in place of power surge.
Current is the amount of electrical charge that flows past a given point in a given time. Current is measured in Amperes, which is Coulombs per Second. Sometimes, erroneously, we use the term current to refer to voltage or power. Voltage is Joules per Coulomb. Power is Joules per Second, or Voltage times Current.
authority
A DC-to-DC converter is the general term for a device that changes DC voltage at one level to another.
