A small coil has a self-inductance of 10 μH. A sinusoidal current of amplitude 0.1 A and frequency 1 kHz passes through the coil.
(a) Calculate the emf measured on the coil.
(b) What is the voltage if frequency changes to 100 kHz.
(c) Calculate the emf at 1 kHz for a 10 mH coil.

In the reaction 2C8H18 + 25O2 --> 16CO2 + 18 H2O, the ratio of volumes of O2 to CO2
What is the expansion factor of this scheme and what are its visual threshold values?
When the supply frequency is increased to 90 Hz, while keeping the flux density constant, the total core loss is found to be 3000 W. Determine the hysteresis and eddy-current losses separately at both frequencies.
Assuming Rocky Mountain Tire Center orders (answer from above) tires per order, what is the total annual cost?
The product is neutralized and washed with water to remove salts. The washed product is usually separated by batch distillation, in which unreacted feeds are recovered first, followed by product, and a polymeric waste is left as residue. The batch..
Calculate the voltage at the primary high voltage terminals if the secondary supplies rated secondary current at 230 V and unity power factor.
The solubility of sodium bicarbonate in water is 11.1 g NaHCO3/l0O g H2O at 30°C and 16.4 g NaHCO3/100 g H20 at 60°C. If a saturated solution of NaHCO3 at 60°C is cooled and comes to equilibrium at 30°C, what percentage of the dissolved salt cryst..
