Draw a schematic of a circuit that converts the thermistor resistance to a measurable voltage.I suggest basing it on the only circuit you have studied so far: the voltage divider.Assuming that you have a negative-thermal coecient (NTC) thermistor and that you wanthigher temperature to result in higher voltage, which of the resistors in a voltage divider isthe thermistor and which is a fixed resistor?Use the proper thermistor symbol and put the thermistor part number on the schematic.(For the final report, update this schematic with the resistor value chosen in the lab.)

We consider the circuit diagram shown in the figure below:Here, RThermistor denotes the variable…

An AC electric motor is connected to a 240-V, 60-Hz source. A clamp-on ammeter with a peak hold function reveals that the motor has an inrush current of 34 A when the motor is first started. Your job is to reduce the inrush current to a value of 20 A by connecting a resistor in series with the motor. The resistor will be shunted out of the circuit after the motor is started. Using an ohmmeter, you find that the motor has a wire resistance of 3 . How much resistance should be connected in series with the motor to reduce the starting current to 20 A?
An office building uses a bank of 63 lead-acid cells connected in series with a capacity of 80 amp-hours each to provide battery backup for their computers. The lead-acid cells are to be replaced with nickel-metal hydride cells with a capacity of 40 amp-hours each. How many nickel-metal hydride cells will be required to replace the lead-acid cells and how should they be connected?

Using the circuit in the figure, the experimentercalculates the internal resistance Rx of the structure “X” as“U/I” (U and I: Readings of the instruments). Can you please explain the solution in detail? Thanks
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. 9 V b. 8 V c. 4 V d. 3 V
2. In a circuit that contains only resistors in parallel, some of the current in the circuit will go through each branch of the parallel resistors, as dictated by Kirchoff's Junction Rule. Furthermore, the potential difference provided by the battery is the potential difference across each branch of the parallel resistors (notice there is no potential drop between the branches). Assume the batteries supply a potential difference of AV = 3.0 V, and use Ohm's Law along with the currents measured through resistor R1 in circuits 4a, 4b, and 4c to determine the effective resistance in this branch (the branch that includes R1) of each circuit. Please show the calculation of each. R1 = 150 ohm, R2 = 230 ohm R3 = 270 ohms (don't believe question should need these but providing anyways)
The open-circuit voltage of a particular solar cell is 2.2 V, and the short-circuit resistance (that is, a load resistor is zero) is 1.1 A. What is the internal resistance of the battery? What is the voltage supplied by the battery?
Directions: Complete the table by providing the values for Vab, Vac, Vbd, and Vcd. Refer to Figures a and b. Note that an ideal voltmeter has infinite resistance while an ideal ammeter has zero resistance. You may need to compute for the current in the circuit to find the unknown voltages.
A moving coil ammeter gives a full scale deflection for a current i = 250 mA and its coil has a resistance RC = 0.75 Ω. It is provided with a multiplier resistance Rm that allows a voltage measurement of up to 5 V. What is the value of the multiplier resistance?
Shown below is a typical setup for a solar battery system. Sun’s energy is converted to electricity using solar PV modules. To match the output voltage of the PV module to the battery's, a charge controller is used which is a DC-DC converter. The sun’s output power is given as 1000 W/m2. The solar module has a surface area of 1 m^2 with a conversion efficiency of 10%. A charge controller converts the 20V module voltage to 12V battery voltage, with an efficiency of 84% The battery is 12V with a capacity of 10Ah. Assuming the battery is half empty (or half full, depending on your personality) and the bulb is powered on, how long will it take for the battery to be fully charged? How long can the bulb be powered at night, assuming full battery when the sun goes down and that you can fully drain the battery? (answer in hours)
In the circuit above, the ammeter (A) is an ideal ammeter (so without internal resistance); the voltmeter (V) is also ideal (so with an infinitely large resistance). The two e.m.f. sources have negligible internal resistance. The voltmeter reads a positive value when the voltage of the ++-connector is higher than the voltage of the -−-connector (see picture) The ammeter reads a positive value when the current runs from the ++-connector to the -−-connector. What are the readings of the ammeter and the voltmeter?
