The temperature coefficient of a carbon resistor is 5x 10C if the resistance of a carbon resistor is 500 ohm at find its resistance at 120°C |
|
Answer» this may help you if not than i am sorryExplanation:Insulation resistance is poor with APPROXIMATELY 10^9 Ω (order of MAGNITUDE worse than other types). One more reason for the decrease in the use of this TYPE of resistor, is the high TEMPERATURE COEFFICIENT of around 1200 ppm/° C. |

transparent sphere of radius 6c h is kept on in air and object is placed at a distance from the surface of sphere and its real image is formed at the same distance from the second surface of the sphere find the refractive index of the material of sphere |
|
Answer» Given: A transparent sphere of radius R and refractive index μ is kept in the air. To find the distance from the SURFACE of the sphere where a POINT should be placed so as to form a real image at the same distance from the other side of the sphereSolution:Using the equation, vμ 2 − uμ 1 = Rμ 2 −μ 1 For the REFRACTION at the FIRST surface of the sphere, (air to glass)∞μ − −x1 = Rμ−1 , Here x is the distance of point object from the sphere, as shown in above fig.⟹ x1 = Rμ−1 ⟹x= μ−1R Hence the object should be placed this distance from the surface of the sphere in order to get real image.solution |
