consider a horse pulling a cart; the power of the horse, which combines how fast it can run (speed) and how much it can pull (strength), can be likened to wattage in electricity which combines voltage (electrical pressure) and amperage (flow ...
The resulting power dissipation requires large, expensive, high wattage resistors, which demand additional cooling to keep components and motherboard layers below maximum allowable temperature limits. Power loss may be mitigated by selecting a low value of resistance, however minimum signal amplitude must...

Calculate the instantaneous voltage using the formula: V (inst) = Vo (1-e^-t/T) in which Vo is the power supply voltage, t represents the time the power supply has been on and V (inst) is the instantaneous voltage that exists at the instant the power supply is turned on at t = ...
If you explore this equation, you find that by adding the resistances of the same magnitude, you decrease the resistance of the circuit as a whole. (Picking 1 ohm, or 1 Ω, makes the math easier.) By Ohm's law, this actually increases the current!
If you need an equation to justify an answer, take the wattage (50 watts) divide it by the amperage (4.17 amps) and you'll get 11.99, so 12 Volts is your answer. By anon236948 — On Dec 27, 2011 please give me a clear idea about amps, kilovolts, kilovolt amps and watts. ...
Moreover, shapes of these exponential, progressively reduced Time Constant discharges and points at which they are switched into action are designed to save Wattage of electrical power needed for creating VLF HV test wave envelopes of sinusoidal shape applied across capacitive test loads.
