What is source voltage: Definition and 12 Discussions
A voltage source is a two-terminal device which can maintain a fixed voltage. An ideal voltage source can maintain the fixed voltage independent of the load resistance or the output current. However, a real-world voltage source cannot supply unlimited current.
A voltage source is the dual of a current source. Real-world sources of electrical energy, such as batteries and generators, can be modeled for analysis purposes as a combination of an ideal voltage source and additional combinations of impedance elements.
I have drawn the I-V characteristic graph of the diode. I am facing problems with drawing the load line. For what value of E (Source Voltage), should I draw the Load Line? To get the I-V graph, I had to continuously change E.
The end goal is I need to convert a sinusoidal into a square wave using a zero crossing circuit. I have a voltage that ranges from 0 to 400vrms @70kHz from a capacitor that is part of an induction heater tank circuit. My comparator has a peak differential input of +/- 35v so I need to reduce the...
1) Why does there have to be an inductor to generate a voltage opposing the source voltage? Doesn't the circuit create back voltage without an inductor?
2) In ##U = \frac{1}{2}LI^2 + \frac{1}{2}\frac{Q^2}{C}##
##E = \frac{1}{2}mv^2 + \frac{1}{2}kx^2## where ##x(t) = Acos(wt + \phi)##

Hi everyone, I'm new to this forum so I apologise in advance if I may have posted in the wrong forum or made a similar error.
I recently conducted an experiment with some peers where we measured the voltage across a charging capacitor in an RC circuit over a period of time. The diagram is...

Hello everyone.
I indeed like to understand the things I am learning, and for the love of me, I cannot understand why, according to the formula, capacity of a condenser in a circuit consisted of said condenser and a power source is inversely proportional to the power source's voltage. Could you...
