This is why I almost always use subscripts on voltage and current variables so it's clear that, e.g., relates the voltage across and current through the resistor of resistance R. In a circuit, each...

(which I do understand as per ohm's law). But for the dependent source, there is no resistance. I know if you are using mesh analysis, you can assign an arbitrary resistance, say Ro, which will fac...

Without voltage no current will flow in a circuit. More formally, without a voltage difference between two points no current will flow. We understand, for example, that a new battery with a certain...

But the problem is : when i adjusting the regulator circuit without any load (LED) it can show 3,7V or 11,2V (for 3 Leds in series). but when i connected to load, voltage just drop too much and the...

Hi all! I have been trying to solve this circuit with about every method I could think of: node voltage, mesh current, branch current, superposition, and...

I am now trying to tune the circuit to turn on at appropriate level and not over-current the LED at higher signals. I am using a 3mm red LED with max current of 30mA, which is what I get when the l...
