120 Vac, three phase, 400 Hz power supply - how important is balancing load?
We have 208/120 V, 400 Hz outlet. Can I use a single phase from the outlet to power my hardware or do I need to maintain equal load on all phase?
Let's assume that the max current draw is around 6 ...

Looking for alternative analog/digital circuits to drive low impedance with high current
I am looking to drive a load with the specifications as follows:
Load Resistance = 2.2 ±0.3 Ω
Load Current = 1.5-4.5 A
Nominal Load Current = 2 A
The load current should never go below 1.25 A at any ...

Utility of a load resistance for measuring another resistance
In this paper they need to measure the value of an unknown resistance RS, whose value is the output signal of a sensor. However, instead of measuring this resistance directly with a multimeter, they ...

Purpose of 1 kΩ resistor in parallel with load at output of op-amp
As I was reading some op-amp data sheets, I noticed they placed output resistors to ground in some test circuits. These can be seen in the insets of the plots below for the LTC6228 and the LT6202.

Loading problem with circuit simulation
EDIT #1
So I understand now the phenomenon that is happening.
Taking operational stage 2 Switch is OFF.
So there are the 2 cases discussed.
RL = ∞ (exaggerated scenario) the current I1 >> I2 ...

P-Channel MOSFET used as a load switch, practical doubt about Vgs
UPDATE AT THE BOTTOM
in a battery powered project with high current I'm using a P MOSFET as load switch in place of a mechanical switch to prevent inrush current and consequent spark on the switch ...

If batteries are arranged in series in a closed circuit (I.e. with a load, which is constant) why doesn’t the current increase when voltage does?
I guess people have asked slightly similar questions to mine before, but I still haven’t been able to find a complete answer as to WHY the current doesn’t increase even when the voltage in a circuit ...

I am simulating an equivalent model of a laser in LTspice shown below. I am supposed to plot the power at node Pout versus the input current
The issue is I am not able to plot the power without adding the load resistor which is not specified in the equivalent circuit.
Is there any other way to plot the power? If not, then what value of ...
