LA4: (Case Study 4)

Propose a project plan to design a Multimeter and then Design

Your name:

Date:

(Hint: Follow the Design Steps that are mentioned in the LA4PPT Read Me file in order to calculate for your Designed Value (Technical data).)

1. Project Plan

This project is about planning, designing, and reporting a Multimeter which can measure Current (Ammeter) and Voltage (Voltmeter) in a circuit. The problem statements are as follows.

· Design an Ammeter which can read 0-1 mA, 0-10 mA, 0-100 mA, and 0-500 mA.

· Design a Voltmeter which can read 0-1 V, 0-10 V, 0-100 V, and 0-1000 V.

2. Theory

Ohm’s Law will be used (Write ohms Law below).

3. Materials

· Galvanometers: 2 numbers (One for Ammeter and one for Voltmeter). Write the specification (voltage and resistance) of the Galvanometer. You can use the same specification that the Book has mentioned. See PowerPoint.

· Resistors as needed (based on calculation)

· A rotary switch/knob

4. Calculations for designed values (technical data) for Ammeter

Do calculations here. That is find out the values of resistances needed for Ammeter.

4.1 Design (Insert your Figures with designed values (technical data) from PowerPoint for Ammeter below).

5. Calculation for designed values (technical data) for Voltmeter

Do calculations here. That is find out the values of resistances needed for Ammeter.

5.1 Design (Insert your Figures with designed values (technical data) from PowerPoint for Voltmeter below).
