Unit 3 MLR Example

How can you use a DMM to measure different characteristics of electrical components and circuits? Why are these measurements important?

Describe how to place the DMM to measure the current, voltage, and resistance?

What are the nominal resistance and tolerance of a resistor with color bands in the order of violet-green--red-silver from an end of the resistor casing toward the middle? Note: DRAW THE DIAGRAM

What are the relationships of resistance, voltage and current, and the distribution of voltages and currents in each resistor for the different type of circuits.

7. How does the multimeter/voltmeter have to connect to the battery in order to provide an indication? What does this tell us about multimeter/voltmeter use and the nature of voltage? 8. Is there such a thing as voltage "at" a single point? 9. What would you say about a piece of wire if the ohmmeter needle didn't move at all when the probes were connected to opposite ends?

it is the ratio of measured voltage to the measured current of an electrical load circuit. A. Resistance  B. Hot resisitance  C. Cold resistance  D. infinite Resistance

If the measured values for resistors #1, #2 and # 3 are 552, 549 and 549 Ohms calculate the %error (measured difference from expected value as a percentage) for each resistor. Are they within tolerance (or specification) of manufacturer? #1 98.4% #2 97.9% #3 97.9% Yes within specification a. b. #1 1.6% #2 2.1% #3 2.1% Yes within specification #1 1.6% #2 2.1% #3 2.1% No outside specification Ос. Use Ohm's Law to calculate the equivalent resistance of R12, R23 and R123 (as specified in the lab manual) using measured resistances #1 552 Ohms, #2 549 Ohms, #3 549 Ohms R, R2 R,= R12 R23

Fill in the blanks for Ampacity, Voltage, Power and Resistance.

Short circuit is occurred when: Select one: a. The voltage between the two terminals is zero although there may be a nonzero current between the terminals. b. All of the given answers. c. There will be a zero-resistance connection between terminal A and B and therefore the 2 terminals are at the same voltage. d. A pair of terminals connected by a wire (of zero resistance).

On separate sheets of bond paper, draw and write the uses of voltmeter and ammeter.

State the characteristics of voltage and current in a series circuit connection of resistors. State the characteristics of voltage and current in a parallel circuit connection of resistors. please explain it properly.

Voltage drop is the: what is the answer? a. voltage at the end of a circuit b. voltage produced by a source c. maximum potential d. difference in potential between two points

A 50 μA basic D'Arsonval movement with an internal resistance of 500 is to be used as a voltmeter. The value of the multiplier resistance required to measure a full-scale voltage range of 0-5 volts is?

Explain in paragraph the relationships of resistance, voltage and current, and the distribution of voltages and currents in each resistor for the different type of circuits.

28)This multiple choice question from MEASUREMENTS INSTRUMENTATIONS course.

what is the normal resistance measurement range for most DMMs?

The suitability of using a multi-meter to measure current, voltage and resistance.

What is the definition of electrical resistance?

Meter Questions These questions address how to use and read the Simpson and Fluke DMM when measuring resistance. You can get assistance by referring to the meter manuals included at the end of your course packet. If you have any questions, ask one of the Lab staff members. Simpson Model 260 Volt-Ohm-Milliammeter 1. What are the three resistance ranges available on the Simpson meter? When changing resistance ranges on the Simpson meter, the meter must be zeroed using the Zero Ohm's Adjust knob. What is/are the reason(s) for this step? 2. 3. Where is "OQ" on the meter scale – on the left or right end? a. Left b. Right 4. Is the Simpson meter more accurate at the left or right end of the OHMS scale? a. Left b. Right C. The meter has the same accuracy across the entire OHMS scale A meter is set to the "Rx100" setting and the needle is pointing to "200" on the OHMS scale. The technician changes to the Rx10,000 setting and the pointer settles over "1.8". Which is the more accurate reading?…

In the simplest terms you can think of, define what an electrical circuit is.
