Solving a circuit with a directional loop

I came up with the following circuit: Please disregard the labeled values in the diagram - the resistances are identical for the sake of simplicity, and of value $R$, and the voltage has value $V$...

Nodal analysis for current controlled current source

Okay here I go. I just started learning nodal analysis technique but I feel its difficult in solving the circuits consisting of dependent current and voltage sources. Im unable to solve this circuit. ...

Dirac Delta Impulse Response of series RC circuit (Voltage across the capacitor)

I have evaluated the transfer function of an $RC$ circuit, getting the following transfer function: $$H(s)= \frac{1}{1+sCR}$$ the impulse response (i.e. output response to a Dirac's Delta) would ...

When to use Nodal Anaylsis / Mesh / Superposition?

I'm studying these three methods and i'm confused on exactly which one is used when. This is a very broad question. Therefore, could some explain in general terms the difference of the three methods ...

Node Analysis - current calculation

I have a cicuit here that's giving me trouble when finding out what V1 and V2 equal.The book says that I1 is traveling through the 8 ohm resistor (R1) towards ground. But when I build the circuit on ...

Circuit Simulator is being funky

This circuit simulator called "iCircuit" for mac users is showing some weird readings. It's showing a reading of 2.4mA and i'm getting 6mA in my calculations for this circuit I threw up. Am I missing ...

Calculate transfer function with Sine generator

Given this circuit I would like to know how can I find it's transfer function. A method I've considered was to use Node Equations on nodes 1 and 2 , and I have a few things that I don't find clear :...

SuperNode Problem

I'm still having problems with supernodes. Correct me if my logic is wrong. I took the KVL of the circuit which was $-v_1 +2V_o + V_2 = 0$; Afterwards, I did the nodal analysis of both the ...

Electromagnetic induction circuit

In the picture below we see 3 LEDs in a parallel circuit. When the switch is closed only LED 2 and LED 3 are on. LED 1 isn't on because it's a diode in the opposite direction. You observe what happens ...
