Designing Electric Circuits

  1. DESIGN A SERIES-PARALLEL CIRCUIT COMPOSED OF EXACTLY FIVE RESISTORS. THE EQUIVALENT RESISTANCE OF YOUR CIRCUIT MUST BE 125𝛀. CONNECT YOUR CIRCUIT TO A 125V VOLTAGE

SOURCE. PLACE AN AMMETER IN THE APPROPRIATE LOCATION TO VERIFY THE CURRENT OF 1A. SUBMIT THE MULTISIM SCHEMATIC OF THE CIRCUIT VERIFYING THE 1A AMMETER READING.

  1. DESIGN A SERIES CIRCUIT WITH THREE RESISTORS, R1, R2 AND R3, CONNECT TO A SOURCE VOLTAGE, VIN, THAT SATISFIES THE LINEARITY EQUATION VR3 = THE VOLTAGE ACROSS

RESISTOR R3 = KVIN. LET K = .25. SUBMIT THE MULTISIM SCHEMATIC OF THE CIRCUIT VERIFYING THE CORRECT VR3 READING FOR VIN = 10V.

  1. DESIGN A NORTON EQUIVALENT CIRCUIT WITH A SOURCE CURRENT OF 2A THAT DELIVERS A MAXIMUM POWER OF 10W TO A LOAD RESISTOR. SUBMIT THE MULTISIM SCHEMATIC OF THE CIRCUIT

VERIFYING THE CURRENT AND VOLTAGE OF THE LOAD RESISTOR. BE SURE TO LABEL THE CORRECT VALUE OF THE LOAD RESISTOR.

  1. DESIGN A SUMMING AMPLIFIER CIRCUIT THAT SATISFIES THE EQUATION VOUT = 2V1+3V2, WHERE V1 = 1V AND V2 = 3V. CHOOSE A +/-VCC VALUE THAT FORCES THE OP-AMP INTO

SATURATED OPERATION FROM THESE TWO INPUT VOLTAGES. SUBMIT THE MULTISIM SCHEMATIC OF THE CIRCUIT VERIFYING THE OUTPUT OF THE OP-AMP IN SATURATION.

  1. USING MULTISIM, BUILD THE RC CIRCUIT SHOWN IN THE RC TIME CONSTANTS LAB, BUT WITH R1 = 500𝛀 AND C1 = 0.2 MICROF. CONNECT A VOLTMETER ACROSS THE CAPACITOR. SUBMIT

THE MULTISIM GRAPHER IMAGE VERIFYING THE NATURAL AND STEP RESPONSES OF THE RC CIRCUIT. LABEL WHERE TIME = LaTeX: \tau .
