How to Draw a Graph for a Time-Variant Circuit with Multiple Variables?

[electron2]

i solved the previos one

i have this kind of resistor.
v=(cos2t)i+3

i don't know to to draw its grapg

because there are 3 variables
and i don't know why its currect contolled
and not voltage controlled too
..

Can you state the question or problem exactly as it is worded? As you said, there are 3 variables. So simply saying "draw its graph" is not sufficient instruction.

I can offer some guidance on how to approach this type of problem. The first step would be to understand the variables and their relationships in the equation. In this case, we have voltage (v), time (t), and current (i). The equation shows that voltage is a function of time, with a cosine wave at a frequency of 2. This means that as time increases, the voltage will vary in a sinusoidal pattern.

To draw the graph, we need to plot voltage (v) on the y-axis and time (t) on the x-axis. The graph will show a sinusoidal wave with a frequency of 2. The amplitude of the wave will determine the maximum and minimum voltage values. In this equation, the maximum voltage is 3 and the minimum voltage is -3.

As for why this is a current-controlled circuit, it is because the equation shows that voltage is dependent on current (i). This means that the current flowing through the circuit will determine the voltage output. In contrast, a voltage-controlled circuit would have an equation where current is dependent on voltage.

I hope this helps in understanding how to approach and draw a graph for a time-variant circuit. It's important to carefully analyze the variables and their relationships to accurately represent the circuit in a graph.
