If you are referring to the voltage after the rectifiers in a powersupply, it is due to the voltage drop across the rectifiers.
why will Vpk not be exactely equal to the peak voltage of the altenating supply
In a series circuit the current flow in each element is equal but voltage across the each element is differ. In a parallel circuit the voltage across the each element is equal but current flow in each element is differ.
Power, in 'watts'.
They are not equal; they differ by 0.072.
Well, not exactly. "I'm sorry" is exactly equal to "I apologize."
Electric power is not defined as current divided by voltage. Electric power (Watts) is equal to amps times voltage
the source voltage is the voltage that measured exactly after the voltage source , but the terminal voltage is the voltage that measured in the load terminals , which equal to the source voltage minus the drop voltage on the transmission line .
The voltage is greater than the applied voltage, why?
It is equal to exactly 110.
The symbol for "exactly" is "=" which means equal.
They differ by thickness of the aluminum and weight.
The terminal voltage is equal to the supply voltage and there is zero current.
