Apply a test to check if your answer to (b) is correct.8. * The following description of a circuit appears in your experimental laboratory manual. You are required to set the circuit up in order to do an experiment. Before you set up the circuit your teacher asks you to draw, using standard symbols, a circuit diagram of the circuit. In the space provided draw a labelled circuit diagram for the described circuit in the space below. The source of potential difference is two 3V cells connected in series to a switch and two 500 resistors. These components are also in series with three light bulbs in parallel to each other. A variable resistor is placed in series with one of the light bulbs. An ammeter is needed to measure the total current in the circuit. The potential difference across the whole parallel network and across one of the 1000 resistors is to be measured as well.
- ***I already asked this question, but it was done incorrectly as seen by the incorrect answer matching the given answer prior to this. Definitely dissapointing, because it was a waste of a question plus I have to ask the same question again so basically wasted 2.*** A circuit consisting of three ideal batteries with voltages ℰ1,E1, ℰ2,E2, and ℰ3,E3, and three ideal resistors with resistances ?1,R1, ?2,R2, and ?3,R3, is shown in the figure. Calculate the current ?PIP through point P. Let the sign of the current correspond to its direction, with "up" being positive. ℰ1=25.0 V, ℰ2=15.0 V, ℰ3=31.5 VE1=25.0 V, E2=15.0 V, E3=31.5 V ?1=3.20 kΩ, ?2=17.0 kΩ, ?3=5.75 kΩa.) Differentiate the connection of resistors in series and in parallelb.) Compare the voltage and current in individual resistors to the total voltage and total current, respectively, in a series connection.c.) Compare the voltage and current in individual resistors to the total voltage and total current, respectively, in a parallel connection.d.) Describe how the total resistance is obtained in a series and in a parallel connectionAn ammeter is (incorrectly) inserted into a circuit as shown.a. What is the current through the 5.0 Ω resistor?b. How would you change the circuit to correctly connect the ammeter to measure the current through the 5.0 Ω resistor?
- How would the value of each of the four following physical quantities change over time after the switch is closed? Explain why for each case in 1 or 2 sentences. (You may assume that the resistance of the batteries, the wires, and the switch are negligibly small for this question). a. The voltage across the capacitor, VCAP b. The voltage across the light bulb, VBULB c. The current through light bulb, IBULB d. VBULB + VCAPDetermine the following quantities for each of the two circuits shown below. a. the equivalent resistance b. the current from the power supply c. the current through each resistor d. the voltage drop across each resistor e. the power dissipated in each resistor R, R2 R3 R4 (a) R, R2 R3 R4 (b) 1002, R4 = 50N, and that they are connected to Assume that R1 = 202, R2 = 402, R3 a battery with a voltage of 120 VSolve the unknown quantities I1, I2 and I3 from the circuit in the picture. b) What is the voltage between points A and B?
- Switching In the figure below you see a circuit with a battery (V), a capacitor (C), and two resistors (R1 and R2). The circuit has a switch that can be in two positions: switched to touch point A or switched to touch point B. By setting first the switch to A you can charge the capacitor, and then switching it to B you discharge the capacitor through the resistor. (This is the simple mechanism behind a camera flash, you can imagine the resistor R2 as a lightbulb that would "flash" for a short time when there is a current through it.) R, C R, Assume the capacitor is initially uncharged, you now close the switch to position A. What is the a) potential difference across the capacitor after a long time that the switch has been closed? b) ) What is the charge on the capacitor after the switch has been closed to position A for a long time?Why should an Ammeter be connected in series to a circuit to measure the current in the circuit? Why must a pendulum swing through a small angle? *ASK YOUR TEACHER PRACTICE ANOTHER The figure below shows a battery connected to a circuit. The potential difference across the battery and the resistance of each resistor is given in the figure. 25.0 V 13.0 Ω 13.0 Ω 7.50 Ω 7.50 Ω 20.0 Ω A rectangular circuit begins at its left side at a 25.0 V battery with the positive terminal on top. From the battery, the circuit extends up and to the right to point b. The circuit continues rightward from point b and splits into three parallel vertical branches. The leftmost branch has a resistor labeled 13.0 Ω, the middle branch has a resistor labeled 7.50 Ω and the rightmost branch, from top to bottom, goes through a resistor labeled 7.50 Ω, point c, and a resistor labeled 20.0 Ω. The three branches recombine, the circuit extends to the left passing through point a, bends upward to a resistor labeled 13.0 Ω and reaches the negative terminal of the battery. (a) What is the magnitude of the potential difference (in V) between points a and b in the…
