By Alix Loane.As discussed earlier, a digital circuit represents and manipulates information encoded as electric signals that can assume one of two voltages logic-high voltage (or Vdd) and logic-low voltage (or GND). Parallel circuits have one common voltage across all the branches but the individual branch currents can be different.For a parallel circuit with any number of branch currents we can then write an equation for calculating the total current (It) A parallel circuit has more than one path for current flow. The same voltage is applied across each branch.A series-parallel circuit has some components in series and others in parallel.

Current (Total Flow) is equal to the flow of all the current paths. As for your equation IE/R What is your Rtotal? or you Esource? In a parallel circuit when E is constant there would be no voltage change in the circuit as resistance doesnt effect it. No equations for voltage and current are given. Youll have to remember that the current is the same at every point in the circuit and the voltage drops add up to the total voltage provided by the voltage source.Each would see a voltage drop of 12 V. Rules for Parallel Circuits Use Ohms law to derive equations for the total resistance of multiple resistors in series and parallel circuits.The current follows different paths to each resistor. In a parallel circuit, the voltage drops across each resistor are equal.

A circuit is a closed path for the flow of charge. It usually contains a source of potential difference and a resistor it may have other devices such a voltmeter or an amp meter. There are two types of circuits the series circuit is one that only has one path for the current to flow through. According to Ohms law, the voltage drop, V, across a resistor when a current flows through it is calculated by using the equation VIR, where I isThe total resistance in a parallel circuit is less than the smallest of the individual resistances. Each resistor in parallel has the same voltage of the It should be noted that the equation for nding the Voltage drop in a series circuit cannot be used for a parallel circuit. But because the Voltage drops are the same as the Voltage source, an equation is not needed. Learning with Purpose. Slide 11. Power in parallel circuits. Power in each resistor can be calculated with any of the standard power formulas. Most of the time, the voltage is known, so the equation 2 is most convenient.

Simple Parallel Circuit Lets start with a parallel circuit consisting of three resistors and a single battery: The first principle to understand about parallel circuits is that the voltage is equal across all components in the circuit. The equation given for calculating the total current flowing in a parallel resistor circuit which is the sum of all the individual currents added together is given asSo a parallel resistor circuit having N resistive networks will have N-different current paths while maintaining a common voltage across itself. Circuits with impedances: (a) voltage divider, (b) current divider, (c) series/ parallel circuit, and (d) circuit with dual supplies. Lets consider the current divider circuit in Fig. 3-3b now.
