Someone suggested using a 5,000 muF capacitor to generate flash for a camera. A capacitor is to charged slowly and completely up to a potential difference of 10V. At the time of generating flash, all stored energy of a capacitor is discharged through a discharge tube in such a manner that flash only time 100 mus to release the total energy of the capacitor. Calculate the power of camera flash.

When the chemicals in the electric cell are used up, the electric cell stops producing electricity. The electric cell is then replaced with a new one. In case of rechargeable batteries (such as the type used in mobile phones, camera and inverters), they are used again and again. How?

In the following item, passage consists of six sentences. The first and sixth sentence are given in the beginning as S_1 and S_6 . The middle four sentences in each have been jumbled up. These are labelled P, Q, R and S. You are required to find out the proper sequence of the four sentences and indicate your answer accordingly on the Answer Sheet. S_1 : If you want to film a scene in slow motion you run the camera twice as fast as usual, which sounds ridiculous but isn't. S_6 : On the screen, everything appears at half the speed at which the camera recorded it when it was filmed. P: If you are filming in slow motion, however, the camera runs at twice the normal speed, yet, in spite of this, the projector which shows the film will be run at the normal speed, and this means that the projector will show the film at half the speed at which it was photographed. Q : This is because the camera which took the pictures and the projector which shows them run at the same speed. R: When a film camera is running at normal speed, it takes twenty-four pictures a second. S: When the film is run through the film- projector in the camera twenty-four pictures a second appear on the screen. The proper sequence should be :
