A coil havingof a resistance of 100 and an inductance of 200mH.
If an alternating voltage, v, givenby v=200sin500t volts is applied across the coil, measure
(a) The circuit impedance,
(b) The current flowing,
(c) The p.d. across the resistance,
(d) The p.d. across the inductance and
(e) The phase angle between voltage and current.
The number of electrons in one molecule of are: (1)22 (2)44 (3)66 (4)88 Ans: 22
A pendulum is timed, first for 20 swings and then for 50 swings Time for 20 swings= 17.4s Time for 50 swings= 43.2s Calculate the average time per swing in each case.
Assume a car rolls down a 52.0-m-long inclined parking lot and is stopped by a fence. If it took the car 11.25 s to roll down the hill, what was the acceleration of the car bef
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
How many types of hologen and gas discharge are there? This will depend upon the use of the system. Gas discharge lamps, particularly those with a very small plasma area are pr
Resolution of Forces by Calculation: One vector was resolved into two mutually perpendicular components. So if there are several vectors each can be resolved into two
Consider a person having mass M and holding two balls every of mass m is at rest over a frictionless surface. Now the person throws one ball towards right direction with velocity "
Motion of an object in a straight line is called one dimensional motion. The location of a particle in one dimensional motion can be explained by only one variable (say x). For a p
The topic for the project is to study and do calculation in Rotating Biological Contactor although you may choose a different title for your report. The aim is to research how the
