positive feedback amplifies a change ... can lead to oscillations system instability and saturation

if a loudspeaker is close to a microphone a very loud squeal = + fb

lasers may use same idea

Hi there, i'll do the best I can I hope this answers your question.


Positive vs. Negative Feedback. The key difference between positive and negative feedback is their response to change: positive feedback amplifies change while negative feedback reduces change. This means that positive feedback will result in more of a product: more apples, more contractions, or more clotting platelets ...

Alvin (DSV-2) is a manned deep-ocean research submersible owned by the United States Navy and operated by the Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Massachusetts. The vehicle was built by General Mills' Electronics Group[2] in Minneapolis, Minnesota. Named to honor the prime mover and creative inspiration for the vehicle, Allyn Vine, Alvin was commissioned on 5 June 1964. The submersible is launched from the deep submergence support vessel RV Atlantis (AGOR-25), which is also owned by the U.S. Navy and operated by WHOI. The submersible has made more than 4,400 dives, carrying two scientists and a pilot, to observe the lifeforms that must cope with super-pressures

If this combination of capacitors is attached to a 9 v battery how much energy will be stored on the plates 25 15
Vlad1618 [11]

The energy stored on the plates will be 378.5 J. The combination of capacitors is in series.

<h3>What is a capacitor?</h3>

A capacitor is a device that can store electrical energy. It is a two-conductor configuration separated by an insulating medium that carries charges of equal size and opposite sign.

An electric insulator or vacuum, such as glass, paper, air, or a semiconductor termed a dielectric, can be used as the non-conductive zone.

The complete question is;

"If this combination of capacitors is attached to a 9.00 V battery; how much energy will be 25 μF 15 μF stored on the plates?"

If the two capacitors are in series the equivalent capacitance will be;

\rm \frac {1}{C} = \frac{1}{C_1}+\frac{1}{C_2} \\\\ \rm \frac {1}{C} = \frac{1}{25}+\frac{1}{15} \\\\ C = 9.375

Energy will be stored on the plates;

\rm E = \frac{1}{2}CV^2 \\\\ E= \frac{1}{2} \times 9.375 \mu F \times ( 9 \ V)^2\\\\E = 378.5 \ J

Hence the energy stored on the plates will be 378.5 J.

An 5kg object is 6 meters up hill. Find potential energy
Mila [183]
Potential Energy = mass * 9.81 * height
(9.81 is the acceleration due to gravity on Earth)

PE = 6 * 9.81 * 6 = 353.16 J
