State the principle of working of a transformer. Can a transformer be used to step up or step down a d.c. voltage?

Every business needs to take the decision regarding the investment in current assets i.e. the working capital. Current assets refer to the assets that are converted into cash or cash...

The waste of living organisms like cow dung, various plant materials like the residue after harvesting of crops, vegetables waste and sewage etc. form biomass. During the decay of biomass,...

B alone finish work in x days A alone work in x - 5 A one day works= 1/(x-5) and B one day works = 1/x A+B one day work = 1/6 so, 1/(x-5)...

(a) :- In a common base amplifier, the phase difference between the input signal and output voltage is zero.

(i) The working of optical fiber is based on total internal reflection.  Statement: When a light ray goes from denser to rarer medium at an angle greater than critical angle, the...

Principle: When current (I ) is passed in the coil, torque τ acts on the coil, given by τ = NIABsinθ  where θ is the angle between the normal to plane...

Working of meter bridge is based on Wheatstone bridge. The error may be minimised by taking balancing length near the middle of the bridge

The principle of transformer is based upon the principle of mutual induction which states that due to continuous change in the current in the primary coil an emf gets induced...

(a) Washing machine works on the principle of centrifugation. Centrifugation is a process that involves the use of the centrifugal force for the separation of mixtures with a centrifuge, used...

On the basis of implication, the two can be differentiated unity of command is related to the functioning of an individual employee only but unity of direction the entire organisation.
