In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component. [ 1 ] Consider a very simple circuit consisting of four light bulbs and a 12-volt automotive battery .
In each circuit, there is a 9 V battery and two 500 Ω resistors. In the series circuit, the resistors subtract voltage and the current is equal everywhere. In the parallel circuit, each resistor provides additional conductivity, so the current through each of them is summed and the voltage is equal everywhere. See Series and parallel circuits.
The solution principles outlined here also apply to phasor analysis of AC circuits. Two circuits are said to be equivalent with respect to a pair of terminals if the voltage across the terminals and current through the terminals for one network have the same relationship as the voltage and current at the terminals of the other network.
A simple electric circuit made up of a voltage source and a resistor. Here, =, according to Ohm's law. An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances ...
Figure 1: Schematic of an electrical circuit illustrating current division. Notation R T refers to the total resistance of the circuit to the right of resistor R X.. In electronics, a current divider is a simple linear circuit that produces an output current (I X) that is a fraction of its input current (I T).
It is constructed from four resistors, two of known values R 1 and R 3 (see diagram), one whose resistance is to be determined R x, and one which is variable and calibrated R 2. Two opposite vertices are connected to a source of electric current, such as a battery, and a galvanometer is connected across the other two vertices. The variable ...
However, the series resistors R M1 and R M2 are low Ohmic resistors (like in the photo) meant to pass current around the instruments M1 and M2, and function as shunt resistors to those instruments. R M1 and R M2 are connected in parallel with M1 and M2. If seen without the instruments these two resistors would be considered series resistors in ...
This circuit does not have a resistor like the above, but all tuned circuits have some resistance, causing them to function as an RLC circuit. An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that ...
