A capacitor and a resistor that are in series are initially connected to a power supply with 22 volts. The power supply is then cut-off and the capacitor begins to discharge through the resistor. At t = 20 s, the voltage across the capacitor drops to 7 volts. What is the resistance of the resistor, in mega ohms (MΩ) if the capacitance, C = 7 μF ? Please give your answer in two decimal places.
A resistor and capacitor are connected in series to a power supply of 50 Volts. The resistor has a value of 30000 ohms and the Capacitor is initially uncharged. After a time of 16.0 seconds, the capacitor is charged 72% fully charged. a) What is the capacitance of capacitor in this circuit? b) What is the time constant of this system? c) What is the current through the resistor at t= 20.0 seconds? d) What is the potential difference across...

Q1. You are given a 12 V DC power supply. You are expected to develop a voltage divider to achieve a voltage of nominal 5V value using a pair of resistors from the E 12 range, with the restrition that you are not expected to draw a current of more than 1 mA from the 12 V DC supply i. Develop a simple circuit showing the possible values for each resistor pair, and the range of the DC output possible...
If you were given a hardwired RC circuit with unknown values for the resistor and capacitor (and did not have a DMM to measure the resistance or capacitance), write up a procedure for how you would determine the range of frequencies sufficient to collect data in order to graphically determine the cutoff frequency.
(a) A capacitor of capacitance 220 μF is connected in series with a 150 kΩ resistor, a switch and an ammeter. A d.c. power supply of negligible internal resistance is connected to the circuit as shown below 1 50 kΩ 220HF A stopclock is started and after 10 seconds the switch S is closed Ammeter readings are noted at regular intervals until a time of 80s is shown on the stopclock. The graph below shows how the current in the...
your supervisor assigns you to determine what element is in a box (i.e.,supply or load and type and size.) you are given a multimeter which can measure amps, voltage, and ohms, a resistor, and a power supply. describe the process to determine what's in the box.
Question 1: multimeter sampling when measuring voltage from a function generator A. How often do you think the meter samples? B. What do you thinking the steps are for the meter to take a sample, convert it into numerical measurement and display it on the screen?
A series resistor-inductor-capacitor circuit (see Fig. 1) can be described as a linear system, in which, for constant voltage, the current across the components follows the equation Ꭱ d . 291(t) + (t) + 'I dt 17 1 DV Cl(t) = 1 + (1) where I is the current, R the resistance, L the inductance, C the capacitance and dv/dt the rate of change of the voltage at the power source.
