consider a capacitor C with an initial charge Q being discharged through resistance R. Determine after how many time constants will the charge of the capacitor drop to 10% of the initial charge. Determine after how many time constants the energy in the capacitor will be 10% of the initial charge energy. explain any differences in the number of time constants for the charge and energy to drop by the same percentage.

A supercapacitor is an electrical energy storage device. A supercapacitor, initially charged to 9.8 thousand millivolts, supplies power to an emergency beacon. The power draw from the load causes the capacitor to lose 4.4% of its charge every minute. When the charge drops below 7 hundred millivolts the beacon will cease functioning. How long will the beacon last after it is activated (your final answer should be in minutes). Round your answer to the nearest minute.

1) Propose and draw a circuit of a resistive current divider in half

Choose the TRUE statement: a) A capacitor is rated according to its maximum allowable voltage and capacitance value. Increasing the distance between the plates of a capacitor would yield a higher O b) capacitance. O) Electrolytic capacitors are non-polarized. O d) The major reason for using electrolytic capacitors is that they have a very low d) capacitance but can handle very low voltages.

3. A 5.6 µF capacitor is charged to 1000 V. Determine the initial stored charge and energy. If this capacitor is discharged to 0 V in a time interval of 1 µs, find the average power delivered by the capacitor during the discharge interval.

1. A Capacitor rated at 50-uF is being charged by a constant current of 2 mA. What will the voltage across the Capacitor be after 3 mins?

2. What type of energy is stored up in a capacitor? In a storage cell? In an inductive circuit? Why are capacitors not used in place of secondary batteries?
