Lab Report 1

The circuit displayed below is comprised of resistors, a battery,  capacitors and a single pole double throwswitch (SPDT). When switch is in the position of A, the battery is connected to the circuit. When the switch is in the position of B, the battery is then replaced with a wire. In the beginning, the switch is open, and all capacitors are firstly uncharged. The switch is then flipped in the position of A, so the battery is in the circuit. Then, 30.0 seconds after the switch is then submitted to the position of A, what will the potential difference be beyond C3?

Only D and E

Now let's try using a pack of AA batteries (1.2 V output voltage and 0.2 Ohm internal resistance each) to replace the lead-acid battery. In order to match the car lead-acid battery, first, 10 such AA batteries need to be connected in series to form a 12V cell, while 50 such cells need to be connected in parallel (as shown in picture above; the total of 500 AA batteries are used). Find the power that is supplied to the same "car starter" using this pack of AA batteries. (Hint: for the second question, you need to find the total voltage and the internal resistance of the whole pack; you also need to find the resistance of the "car starter"; this can be done using the data of the first part of this problem)

100 150 + VA- a + -7V, 81. 52 Figure 2 shows a simplified model of a gas-discharge lamp. One characteristic of these lamps is that they exhibit negative resistance; in other words, as current increases the voltage drops further, making such lamps inherently unstable. As such, a current-limiting ballast is required. For the connection shown in the figure: 1. Find the equivalent Thevenin circuit of the lamp. 2. Find the ballast resistance needed to limit the current drawn from a 24-volt source to 6 amperes.

LED flashlights use "white" LEDs which have a diode voltage drop of 4.0V. A LED flashlight has the circuit illustrated and will run off several AAA batteries that have a 1.5 VDC rating. a. What is the minimum number of AAA cells needed to turn on the flashlight. b. Would you arrange the batteries in parallel or in series? Vdd R + LED V fritzing

A potentiometer consisting of a wire of length L0 has a source of emf, ɛ connected across it. When a standard cell with emf V = 6V, in series with a voltmeter, is connected at one end of the wire and at a distance L = 4 cm along the wire the voltmeter circuit is in balance and the voltmeter reads zero. When the standard cell is replaced by a source of unknown emf the new balance length is found to be 6 cm.   What is the unknown emf? Select one: a. 8 V b. 9 V c. 4 V d. 3 V

Consider the circuit in the figure. Initially switches S1 and S2 are open. Specify whether the readings on the ammeter and voltmeter increase or decrease (in comparison to the initial state) under each of the following conditions (Explain your answers): (a) S1 is open, S2 is closed(b) S1 is closed, S2 is open(c) S1 and S2 are closed

This is a practice problem from the Introduction to Electronics course in my Electrical Engineering program. Could you please walk me through the steps of solving it so that I can solve more complicated ones in the future? Thank you for your assistance.

Help me answer, I want to check my solution To get the contribution of the 75V source to iR, we first kill the 50mA source. What is the resulting equivalent resistance in series with the 75K resistor (in Kohms)  To get the contribution of the 75V source to iR, we first kill the 50mA source. What is the resulting value of iR (in mA)? What is the nodal equation for Vx? What is the Thevanin voltage in (Volts) and Thevanin resistance in (Kohms)?

Two batteries, A and B, are connected in parallel and an 80 ohm resistor is connected across thebattery terminals. The e.m.f. and the internal resistance of battery A are l00V and 5 ohm respectively,and the corresponding values for battery B are 95V and 3 ohm respectively. Find (a) the value anddirection of the current in each battery and (b) the terminal voltage

How do principles of duality apply in the study of electrical circuits, especially in the context of current and voltage?

Can you please do (c)  Calculate the total power consumption of your circuit. I attached a photo of the circuit ect

Please answer d,e,f

In a series circuit, certain general rules may be stated with regard to quantities of voltage, current, resistance, and power. Express these rules, using your own words: "In a series circuit, voltage..." "In a series circuit, current..." "In a series circuit, resistance..." "In a series circuit, power..." For each of these rules, explain why it is true.

Shown below is a DC circuit that contains a number of switches. Each switch is resistanceless when closed. All of the connecting wires may be considered to have zero resistance. All of the resistors shown are identical. The circuit contains an ideal voltmeter. The diagram shows all of the switches open. Beside the diagram are eight different switch configurations for the circuit. Rank these configurations in terms of the voltmeter reading. That is, put first the configuration for which the voltmeter gives the largest reading, and put last the configuration for which the yoltmeter gives the smallest reading. If two or more configurations produce the same voltmeter reading, give these configurations equal ranking.
