How is concept of voltage in electrical circuits is related to the concept of energy

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?

Using the diagram below and the component photos from page 4, draw the realistic experimental setup you will use in this lab.   Draw the actual apparatus with wires and other electrical elements, connected as they will be on your lab table.  Be sure to label components, junctions, and distances as appropriate.

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

what is the causes of voltage drop

Q1.) a) PMMC meter has (10mA) half scale current deflection and (1500) internal resistance. Use this meter to design a dc multimeter of indirect ammeter and direct voltmeter methods to measure the following ranges of current and voltage: 50mA, 100mA, 1A, 5V, 50V, and 150V. Draw the circuit diagram of this multimeter with a control switch that can be used to measure either current or voltage.

One of the following electrical tools is used to create circuits without soldering: Circuit Board O Soldering Tool o jumper wires O Test Leads & Clips

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

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?

4. Four cells each of 2.10 volt internal emf are parallel connected together to make a battery. The internal resistances are 0.004, 0.005, 0.003 and 0.0025 ohm. Calculate for parallel connections: (a) internal emf and resistance of the single equivalent cell (b) current for a terminal voltage of 1.95 volts, (c)current in each cell

The convention for voltmeters is to use a black wire for the negative reference terminal and a red wire for the positive reference terminal. Explain why two wires are required to measure a voltage. If the wires into the voltmeter are swapped by accident, what will happen during the next measurement?

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

What will this voltmeter register when connected to a battery as shown (assume a battery voltage of 6 volts)? Explain your answer. va Follow-up question: what does this tell you about the nature of voltage, and how it is measured?

leaving a freevway. Current from the opposite side must travel further, weakening the potential on that side. This creates a potent the motor in that direction, causing the motor to spin. O Only the side where the switch is closed forms a cormplete circuit, so the motor must spin in that direction.

There is an RL circuit with a switch 2-volt battery, a .15 H inductor, and a 60-ohm resistor. How long after the switch is closed would there be 10 milliamps in the circuit?

In the figure below you see the sketches for the front and back of an electrical circuit board. The board is cut into a trapezoidal shape and is made of plastic. On the back of the board there is conductive paint shown here in green. On the front there are some resistors and capacitors, in addition to terminals for inserting the leads from a DC power supply. The legs of the resistors and capacitors go through the holes on the board and are soldered to the conducting paint on the back side. You also have a multi-meter which you can use as an ammeter or a voltmeter. 16 v 4700 16 10 8 O- 7 3. 6. 4 O+
