What is Dependent current source: Definition and 20 Discussions
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.
A current source is the dual of a voltage source. The term current sink is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source driving a resistive load. There are two types. An independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
Hello,
I came up with a circuit that has two independent voltage-controlled current sources. I want to calculate voltage gain: ##G_{U} = \frac{U_{2}}{U_{1}}##. Moreover, I want to practice the nodal method at the same time. Below I'm sending schematic with marked nodes V1, V2, V3 and V4.

Hello,
I want to calculate the Thevenin/Norton equivalent of a circuit with a dependent current source.
I tried to analyse the circuit using loop equations but i don't know how to calculate the voltage drop across the current source.
Any help would be appreciated.

I need to find the voltages (if any) and currents of these circuit, but particularly Io
I do know that I have to use KCL bot I don't know how, can somebody help me with a node or somethinghttps://www.physicsforums.com/attachments/c2-jpg.80412/

Homework Equations
Pmax = ((VTh)2)/(4RTh)
Rparallel = (R1R2)/(R1 + R2)
KCL ΣI = 0
KVL ΣV = 0
The Attempt at a Solution
Okay, so to find RTh, I remove all independent sources and set the "terminals" at R to have a 1A current running through them. Since there is a 30kΩ...
For this problem, I added in an external source, and found an expression for the external current in terms of ix. Then I divided Vex/iex to get the Rth. Then I did superposition to find the Vth. I had some troubles getting rid of the extra currents, particularly i3 and i2. I was wondering if...

V=IRThe Attempt at a Solution
First I found Vs = 9*sin(14*0.782)=-8.989817V (with t in radians)
Since Rpi is in parallel with the Vs, its voltage Vpi also equals to -8.98917 V.
Since the...

I have a circuit with 3 meshes for which I have to find the mesh currents, and I have.
However, I just thought that there might be a voltage drop over the dependent current source in the circuit, which would change the mesh current equations.
The CCCS is shared by two meshes.
