CIRCUITS HW (1)

If you wanted to measure the voltage of a resistor with a voltmeter, would you introduce the voltmeter to be in series or in parallel to that resistor? Explain. What about for an ammeter?

39. You and your lab partner have built the circuit shown in Figure 1.56. The three resistors, R1, R2 and R3 all have resistances of 1 k2, while the two voltage sources have 5 V and 3 V (as shown). The circuit has two output terminals, A and B. Answer the following questions about the circuit. (NOTE: The orientation of the voltage sources is important.) (a) What is the voltage drop across R1 R2 R3 A 5 V 3 V B Figure 1.56: The circuit for problem 39. R3? (b) What is the current flowing through R1? (c) Sketch the Thévenin equivalent circuit as seen looking into the terminals A and B. What is the Thévenin voltage, Vth, of the circuit? (d) What is the power supplied by the two voltage sources? (e) In order to safely determine the Thévenin resistance of your circuit, you connect a fourth resistor, R4 = 1 k2, between A and B. Using your trusty yellow DVM, you measure a potential difference across R4 to be 0.4 V. Using %3D

1. LED flashlights use "white" LEDs which have a diode voltage drop of 4.0V. An LED flashlight has the circuit illustrated and will run off of several AAA batteries that have a 1.5 VDC rating. a. What is the minimum number of AAA cells are needed to turn on the flashlight. 4/1.5 = 2.65 /3 b. Would you arrange the batteries in parallel or in series? Series a. What series resistor will give the specified LED current? (67 K 70 L b. What is the power dissipated by the resistor you selected in part a? Vdd fritzing 2. In the previous diagram for an LED circuit, the power supply is a 9V battery and we are using a Red LED whose voltage drop is 2V. The specification sheet for the LED recommends that the "ON" current should be 10 milliamps. c. What is the power dissipated in the LED? R + LED V 1

1. Please respond to question in attached image.  Thank you.

1-1.1 A six-cell storage battery having a nominal terminal voltage of 12 V is connected in series with an ammeter and a resistor labeled 6 S2. PROBLEMS 39 a) List as many random quantities as you can for this circuit. b) If the battery voltage can have any value between 10.5 and 12.5, the resistor can have any value within 5% of its marked value, and the ammeter reads within 2% of the true current, find the range of possible ammeter readings. Neglect ammeter resistance. c) List any nonrandom quantities you can for this circuit.

can you help with this tthank you

Please break this down for me as much as possible, im struggling to grasp kirchhoff's, thank you.

3. The figure on the left below shows a schematic diagram of a battery. The voltage measured by U1 is called the terminal voltage given R1 = 1 ohm. In the figure on the right below, the terminal voltage of each of the battery-resistor combination is Vr = 1.5 volts. Find the following: a. The current passing through R5. b. The currents passing through R1 and R3 C. The voltage across R1. d. The voltage of the battery EMF. e. The percentage of voltage loss ot the battery due to the internal resistance R1. The power dissipated by the internal resistance R1. g. The power dissipated by R5 if R1 = R2 = R3 = R4 = 0. h. The percentage of power dissipation loss due to the four resistors R1, R2, R3, and R4 f. R1 R3 S10 R1 U1 1.500 EMF EMF R5 100 V1 R2 $10 EMF R4 EMF EMF

So this question is how to complete these instructions given the lab procedure put in the first picture below. The second picture is all the recorded data. The A and B columns are the 1K ohms resistor and the C and D columns are the 5.1K ohms resistors. I am having a hard time being able to get a graph set up the way they would like it I hope someone can help thank you.   1.Use your data to create graphs of current versus voltage for the two resistors. Note that voltage is the independent variable and it must be plotted on the horizontal axis. Use linear scales and label them properly.2. Draw the single "best" straight line through the data points for each resistor. DO NOT "CONNECT THE DOTS!" Your straight lines may not necessarily touch all, or even any, of the plotted data points. Make sure that all scales are properly labeled and that each line is labeled according to the nominal resistor value that was used for that data set.3. Choose two convenient points on each of your straight…
