# Раздел: Circuit analysis

## Circuit elements

The basic elements of circuit design are components (resistors, capacitors, and inductors), and sources (voltage and current). We describe these elements as both ideal elements and real-world objects. We also develop precise terminology for how to talk about circuits and label voltages and currents.

## DC circuit analysis

Determine the state of a DC circuit using Kirchhoff's Laws, node voltage method, mesh or loop current methods.

## Natural and forced response

Circuits containing capacitors and inductors change with time. The natural and forced response of RC, RL, and RLC circuits.

## AC circuit analysis

If we limit ourselves to input signals shaped like sines or cosines, we can develop a whole AC analysis method to figure out what happens in circuits with changing signals. The methods are far simpler than solving a differential equation.

### За този урок

Circuit analysis is the process of finding all the currents and voltages in a network of connected components. We look at the basic elements used to build circuits, and find out what happens when elements are connected together into a circuit.
