In the net work three identical capacitors are connected as shown.  Each of them can withstand to a maximum 100V potential difference.  What is the maximum voltage that can be applied across A and B so that no capacitor gets spoiled.​

Answer»

ong>ANSWER:

Explanation:

The potential drop and charge across the 4 u F capacitor is given below when five capacitors are CONNECTED to each other.

Explanation:

A device name capacitor which caches electrical energy into an ELECTRIC field. Capacitor is a submissive electronic element containing two terminals. The result of a capacitor is called capacitance.

[ 6, 4, 8 ] is C = 6 + 4 + 8

                     = 18 u F.

Series -> Potential -> V = 30 / 3

                                     = 10 V.

C -> [ 4, 6, 8 ] -> 11 -> Potential -> equal -> 10 V.

Q = 4 X 10  

 = 40 u C.

For more:

Two capacitor c1=2uf and c2=4uf are connected in series and a potential difference (p.d) of 1200v is applied across it the potential difference across 2uf will be.

Should earth be regarded as wave in light of de broglie equation? Explain.​

Answer»

>

The wave nature of matter is one of the most counter-intuitive concepts in Physics. You have seen examples of both particle nature of light and wave nature of light. You know about the Photoelectric effect due to Albert Einstein’s courtesy.

In the photoelectric effect, the electrons and photons exhibit the PROPERTIES of a particle, just like a billiard ball. But you surely remember the Diffraction experiment and the INTERFERENCE Rings.

Just like how two ripples on the surface of a pond interact. We see the wave nature of light in these cases. It’s an amazing MYSTERY. It even INVOLVES our sight! The gathering and focusing mechanism of light by the eye-lens conform to the wave nature of light. But its absorption by the rods and cones of the retina conforms to the particle nature of light! While we were still struggling to understand this mystery, along came Louis de Broglie to make it even more complicated with his de Broglie Relation.

For uniform circular motion write equation of centripetal force, centripetal acceleration. Also write examples ?

Answer»

ong>Answer:

2: The radial (centripetal) force is constant (like a satellite ROTATING about the earth under the influence of a constant force of gravity). The circular motion ADJUSTS its radius in RESPONSE to changes in SPEED. This means that the radius of the circular path is variable, UNLIKE the case of uniform circular motion

Two lenses of powers +12D ana+1.0D are placed in contact,then the effective power of combination will be 2 points2.5D1.5D0.5D3.25Dn​

Answer»

Solution :-

<P>As PER the given data ,
  • P 1 = 1.2 D
  • P 2 = 1 D

The effective power of the combination

⇒ P = P 1  + P 2

⇒ P = 1.2 + 1

⇒ P = 2.2 D

Points to remember :

  • The focal length of a concave MIRROR is always NEGATIVE
  • The focal length of a convex mirror is always positive

  • The focal length of a concave lens is always negative
  • The focal length of a convex lens is always positive

If the discharge tube is filled with various gases in turn, will the discharge in all gases take place at same electrode potential?​

Answer»

ong>Answer:

Hope This Will Help You

Explanation:

Gas-discharge lamps are a family of artificial light sources that generate light by sending an electric discharge through an ionized gas, a plasma. Typically, such lamps use a noble gas (argon, neon, krypton, and xenon) or a mixture of these gases. Some include additional substances, like mercury, sodium, and metal halides, which are vaporized during startup to become part of the gas mixture. In operation, some of the electrons are forced to leave the atoms of the gas near the anode by the electric field applied between the two electrodes, leaving these atoms positively ionized. The free electrons thus released flow onto the anode, while the cations thus formed are accelerated by the electric field and flow towards the cathode. Typically, after TRAVELING a very short distance, the ions collide with neutral gas atoms, which transfer their electrons to the ions. The atoms which lost an electron during the collisions ionize and speed toward the cathode while the ions which gained an electron during the collisions return to a lower energy state while RELEASING energy in the form of PHOTONS. Light of a characteristic frequency is thus emitted. In this way, electrons are relayed through the gas from the cathode to the anode. The color of the light produced depends on the emission spectra of the atoms making up the gas, as well as the pressure of the gas, current density, and other variables. Gas discharge lamps can produce a wide RANGE of colors. Some lamps produce ultraviolet radiation which is converted to visible light by a fluorescent coating on the inside of the lamp's GLASS surface. The fluorescent lamp is perhaps the best known gas-discharge lamp.
