Concept explainers

KVL and KCL

KVL stands for Kirchhoff voltage law. KVL states that the total voltage drops around the loop in any closed electric circuit is equal to the sum of total voltage drop in the same closed loop.

Sign Convention

Science and technology incorporate some ideas and techniques of their own to understand a system skilfully and easily. These techniques are called conventions. For example: Sign conventions of mirrors are used to understand the phenomenon of reflection and refraction in an easier way.

It is common, in the analysis of electrical circuits, to determine voltage drops over resistors specific. If these are passed in circuits formed by independent sources, the principle of superposition is the technique used to solve this problem. He process that, for that, the current sources must be open-circuited and the voltage sources must be shorted. when doing this in the circuit presented below, determine a voltage drop across resistor R1.

. Let a circuit with an open-circuit voltage of 101V be given. 1V voltage is measured on a 1Ω resistor connected to the terminals of the circuit. What is short-circuit current of the circuit?Note: The formal procedure to find the Thevenin and Norton equivalents of a given circuit is to compute the open-circuit voltage (Voc) and the short-circuit current (Isc) at the terminals. Open-circuit voltage is the voltage between the open-circuited terminals and the short-circuit current is the current through the short-circuited terminals.Then the voltage of the source at the Thevenin equivalent is Voc and the current of the source at the Norton equivalent is Isc. The value of the resistance in both cases is the ratio of Voc to Isc (i.e. Rth= Voc / Isc). Another method to find Rth is killing all independent sources and computing the equivalent resistance between the terminals, provided that there is no dependent source in the circuit.
