Slide 1

RESISTIVE CIRCUITS SINGLE NODE-PAIR CIRCUIT ANALYSIS

Slide 2

IN PRACTICE NODES MAY ASSUME STRANGE FORMS THIS ELEMENT IS INACTVE (SHORT-CIRCUITED) LOW DISTORTION POWER AMPLIFIER SINGLE NODE-PAIR CIRCUITS THESE CIRCUITS ARE CHARACTERIZED BY ALL THE ELMENTS HAVING THE SAME VOLTAGE ACROSS THEM - THEY ARE IN PARALLEL

Slide 3

LOW VOLTAGE POWER SUPPLY FOR CRT - PARTIAL VIEW SAMPLE PHYSICAL NODES COMPONENT SIDE CONNECTION SIDE

Slide 4

THE CURRENT DIVISION APPLY KCL USE OHM\'S LAW TO REPLACE CURRENTS DEFINE "PARALLEL RESISTANCE COMBINATION" BASIC CURRENT DIVIDER THE CURRENT i(t) ENTERS THE NODE AND SPLITS - IT IS DIVIDED BETWEEN THE CURRENTS i1(t) AND i2(t)

Slide 5

WHEN IN DOUBT… REDRAW THE CIRCUIT TO HIGHLIGHT ELECTRICAL CONNECTIONS!! IS EASIER TO SEE THE DIVIDER

Slide 6

POWER PER SPEAKER LEARNING EXTENSION - CURRENT DIVIDER CAR STEREO AND CIRCUIT MODEL THERE IS MORE THAN ONE OPTION TO COMPUTE I2

Slide 7

APPLY KCL TO THIS NODE DEFINE "PARALLEL RESISTANCE COMBINATION" FIRST GENERALIZATION: MULTIPLE SOURCES

Slide 9

APPLY KCL TO THIS NODE Ohm\'s Law at each resistor General current divider SECOND GENERALIZATION: MULTIPLE RESISTORS

Slide 10

20k||5k General current divider

Slide 11

FIND THE CURRENT NOTICE THE MINUS SIGN COMBINE RESISTORS COMBINE THE SOURCES STRATEGY: CONVERT THE PROBLEM INTO A BASIC CURRENT DIVIDER BY COMBINING SOURCES AND RESISTORS. THE NEXT SECTION EXPLORES IN MORE DETAIL THE IDEA OF COMBINING RESISTORS

Slide 12

I2 I1 9mA I1 I2 DIFFERENT LOOKS FOR THE SAME ELECTRIC CIRCUIT

Slide 13

I1 I2 I1 REDRAWING A CIRCUIT MAY, SOMETIMES, HELP TO VISUALIZE BETTER THE ELECTRICAL CONNECTIONS I2

Slide 14

Determine power conveyed by source + V _
