Lesson 4 How Voltage Functions In Dc Series Circuits

A maximum output torque b maximum mechanical output power c maximum armature voltage d no load speed at maximum armature voltage.

Lesson 4 how voltage functions in dc series circuits. Replacing voltage sources and associated series resistors with equivalent current sources and parallel resistors yields the modified circuit. Series dc circuits voltage is review of v i and r the amount of energy per charge available to move electrons from one point to another in a circuit. As mentioned in the previous section of lesson 4 two or more electrical devices in a circuit can be connected by series connections or by parallel connections when all the devices are connected using series connections the circuit is referred to as a series circuit in a series circuit each device is connected in a manner such that there is only one pathway by which charge can traverse the. In a series circuit the current remains constant and voltage drops add together and in a parallel circuit the currents add together and voltage drops are constant.

Dc circuits are ones powered by a voltage source that pushes current in one direction only. Start studying lesson 4. Series parallel circuit v1 1 0 vi1 1 2 dc 0 vi2 1 3 dc 0 r1 2 4 100 r2 3 4 250 vi3 4 5 dc 0 vi4 4 6 dc 0 r3 5 0 350 r4 6 0 200 dc v1 24 24 1. Current is the rate of charge flow and is measured in amperes.

Even though component and wiring layout is usually of little consequence in dc circuit function.

How voltage functions in dc series circuits. This lesson will use dc circuit laws including ohm s law and the junction rule to analyze a circuit. Voltage drops add to equal total voltage. Substitute resistor conductances in siemens for resistance in ohms.

Now according to ohm s law. Plan your 60 minute lesson in resistance or circuits electricity with helpful tips from jameson parker. It has a maximum speed of 500 rad s with a maximum current of 2 a. Suppose three resistors r 1 r 2 and r 3 are connected in series across a voltage source of v quantified as volts as shown in the figure.
