Thermistors

A thermistor is a special type of resistor whose resistance is more temperature-dependent than standard resistors. The resistance of the thermistor decreases with increasing temperature. This is the basic principle of thermistors. This allows the thermistor circuit to detect very small temperature changes that cannot be observed with the Resistance temperature detectors (RTDs) or the thermocouples. Since the resistance of a thermistor is temperature dependent, it can be connected to an electrical circuit to measure body temperature. This high sensitivity to temperature changes makes thermistors very useful for accurately controlling and calibrating temperature measurements. In general, resistance increases with increasing temperature in most metals, but thermistors react negatively.

Assume at t=0, a switch in an RC circuit in which the resistor and capacitor are in parallel is closed. how would this affect voltage, charge, and current at t=0 and after a very long time? what if this scenario was the opposite, in which the switch was opened rather than closed? what effect would this have?

What is a Linear Circuit? Simply we can say that the linear circuit is an electric circuit (Links to an external site.) and the parameters of this circuit are resistance, capacitance, inductance and etc are constant. Or we can say the parameters of the circuits are not changed with respect to the voltage and current is called the linear circuit. What is a Non-Linear Circuit? The non-linear circuit is also an electric circuit and the parameters of this circuit differ with respect to the current and the voltage. Or in the electric circuit, the parameters like waveforms, resistance, inductance and etc are not constant is called as Non- linear circuit. Question: Is it possible to apply superposition theorem to nonlinear circuit? If yes, why? and if no, why?

16. Consider a simple RC circuit which has a resistor of 2 ohm and capacitor of 3F. If the initial voltage is 12V then find the charge q(t) is expression. 17. Suppose we have a RC circuit with an alternating voltage V(t) = V_{m} * cos(5t) If the initial voltage is 4V and the resistor has a resistance of 8 ohm and the capacitor is of capacitance 2F then find the charge for the circuit ?
In the circuit shown below, the switch has been open a long time and the circuit is initially in steady-state. At t=0, the switch is closed. R1=0.2Ω, and R2=0.4Ω. The batteries have EMFs E1=1V and E2=3V. The capacitor has capacitance 10 μF. Hint: What is the voltage on the capacitor just before the switch is closed? Note that there is a voltage drop over the open switch. a) What is the voltage over the capacitor before the switch is closed? b) Draw the Thevenin equivalent circuit as seen by the capacitor. c) What is the time constant for charging the capacitor? d) What is the voltage on the capacitor as a function of time?

For the circuit shown in the figure, in which the capacitor is initially fully discharged. If the source voltage V is 17 Volts, the capacitance of capacitor C is 24 mF; and the values of the resistors in Ω are: R1 = 2250 , R2 = 1071 , R3 = 2455 , R4 = 1199 and R5 = 1043 Determine the voltage across the capacitor in Volts after 15 minutes have elapsed since the circuit is energized. ..
2. A parallel plate capacitor with a plate area of 0.13 square meters separated by 1 mm is charged to 9 Volts by a battery, which is then disconnected. The plate separation is then increased to 40 mm.A. Using the expression for the capacitance of a parallel plate capacitor, what do you expect the new potential difference across the plates to be after the increase?B. Suppose you measure the potential difference across the plates after the separation and find it to be 30 V (this should be very different from what you found in part A). This unexpected result can be explained by the effects of “stray capacitance” with nearby objects. Assuming that the stray capacitance can be modeled as a capacitor connected in parallel with the parallel plate capacitor, find the value of this stray capacitance.
Given the circuit below with the switch closed for a long time, then opening at t=0, and with the values R1=129KΩ, R2=128KΩ, R3=103KΩ, calculate the time constant, τ, for the capacitor voltage solution for at t >0.
For the circuit in the figure, initially the switch S is closed in (b), until the capacitor is charged; then the switch goes to point (a) so that the battery is disconnected and the capacitor, resistor and inductor are connected in series. Once S is connected at point (a), find a) the angular frequency of oscillation for the series circuit b) write the equation for the charge on the capacitor as a function of time with the respective values of Qmax, angular frequency Wd and time T c) make the Q(t) graph showing explicitly the envelope of the exponential decay (Hint: use geogebra or an application of your choice to obtain a graph).
