Circuit (Network) analysis is the process of finding the voltages across, and the currents through, every component in the network. Consider using in conjunction with tags for the particular analysis technique(s) in question: "nodal-analysis", "mesh-analysis", "superposition", etc.

RC network simulation
When the transistor initially turns on, it will immediately turn off because C3 nearly simultaneously appears as a short to the collector due to its discharged state. The condition is nearly transient …

How to solve resistance in this circuit?
I find for some students, the angled components are visually confusing. Try redrawing the same schematic with only horizontal and vertical components to see if this helps you to analyze it.
For examp …

Equivalent circuit (series capacitor on inductive pickup)
Since the voltage source for the circuit is AC, the capacitor will exhibit reactance. This reactance is in series with the source so it can have an effect on the output voltage depending on the load p …

Time constant in an RC circuit
Your answers are correct.
Note that you should always number your components in a schematic (e.g. R1, R2, C1, etc). It would make describing this circuit a less ambiguous task.
The time constants in …

What is the capacitor's functionallity in a Simple oscillator where it is conntected to same...
The capacitor is not connected directly to ground. The lamp on one end and the resistor on the other end keep the capacitor above ground potential.
The capacitor is providing feedback from the output …

Why, in a passive circuit with a sinusoidal input, do all voltages and currents have the sam...
Either your premise is false or you have not properly articulated the boundary conditions.
Consider a simple passive device such as a diode. It will exhibit a non-linear transfer characteristic resu …

Using Electricity to generate the right amount of heat
Let's to walk through the math that is required to engineer a solution.
Firstly, as some commenters have pointed out, you didn't supply all of the necessary information.
When you say heat air to …

How does the LC circuit work in a FM transmitter circuit
You schematic does not contain an LC (capacitor and inductor in series or in parallel) circuit. The signal source is a sine wave generator on the left side of the schematic.
If you are simply interes …

Supercapacitor Bank Wont Charge w RPi Load
The 1 ohm balancing resistors are completely inappropriate. Without the capacitor spec sheets, I would estimate their values should be north of 10k each. They may not even be necessary given the 2.7 v …
