How higher load (high R) draws more current when the nature of resistance is to reduce/restrict the current?
Consider a voltage in a circuit(say 100 V) in a closed circuit, and a resistor 10 ohm and a Load of 20 ohm connected across it.
when you turn on the switch, current through them is almost 100/30 (3.33~...

How does capacitive loading and inductive loading differ from resistive load?
A voltage source is loaded when current is drawn from it. Usually we have voltage sources in circuits and not current sources. A resistive load draws current from a voltage source that is a function ...

Power supply for remote load
I tried to design power supply circuit myself because no power supply would do for me (or I'm just unaware). My issue is that I have power supply far away from load and there is no way I can shorten ...

Implementation of a 24 hour variable resistive load fluctuation
I am implementing a DC microgrid with a variable resistive load variation of 24-hours, based on a load profile.
I have implemented it in MATLAB through a variable resistor and a 1-D block to provide ...

Can I connect low-power resistors to achieve a high-power resistive load?
I've designed an 80 W 400 V PFC boost converter and I want to test it with resistive load. but I couldn't find a low-cost high power (20 to 80 watts) resistor in the range of 2k to 10k ohm. Is there ...

Load impedance seen by op-amp
I have a question about the load impedance seen by an ideal op-amp output terminal in inverting configuration.
When calculating the load impedance, we set Vin = 0;
In one way I could say that the ...

Usually Geiger tubes have a recommended 1 to 5 megaohm anode load. What determines that value and what is the effect of increasing the value?
I think title is sufficient. Changes? Dead time, signal out amplitude, plateau character, etc.

Is there a way to somehow "isolate" a voltage drop?
I have a small issue with voltage drop. I'm working on a project, where I have five resistive wires (approx. 8 ohms each) connected to li-ion battery pack in parallel. The battery pack outputs 16.8V ...

How do I calculate load resistance?
I'm here with yet another problem. This time I can't figure out what the question wants. I've calculated the Thévenin equivalent, however I can't work out how I should calculate the RL.
Is the load ...
