  • First-Order RC and RL Transient Circuits When we studied resistive circuits, we never really explored the concept of transients, or circuit responses to sudden changes in a circuit. That is not to say we couldn’t have done so; rather, it was not very interesting, as purely resistive circuits have no concept of time.

  • The impedance, Z, is the sum of these vectors, and is given by: The current and voltage in an RLC circuit are related by V = IZ. The phase relationship between the current and voltage can be found from the vector diagram: its the angle between the impedance, Z, and the resistance, R.
In DC circuits, we can represent the load with a resistor having resistance of RL ohms. Similarly, in AC circuits, we can represent it with a complex load having an impedance of ZL ohms. We can calculate the efficiency of maximum power transfer, $\eta_{Max}$ using following formula.

Sep 02, 2020 · Starting from the circuit schematic, as usually drawn here: Something which is not shown is the decoupling capacitor from +12v to 0v. The purpose of the decoupling capacitor is to remove any signals from the 12v line, in other words, it creates a very low impedance (short circuit) at signal frequencies. If only two components are present, it's either an RC circuit, an RL circuit, or an LC circuit. The overall resistance to the flow of current in an RLC circuit is known as the impedance, symbolized by Z. The impedance is found by combining the resistance, the capacitive reactance, and the inductive reactance.

Note that L1 and L2 form a parallel circuit. The formula for adding impedances in parallel is However, the formula for adding admittances is simpler, where y = 1/z We will use the ability of the Smith chart to calculate admittances and add them. 1 ztot = 1 z1 1 z2 ytot = y1 y2
