commercial ac unit

Commercial Unit of Energy - The SI unit joule is too small to express very large quantities of energy. Hence we use a bigger unit called kilowatt hour (kWh) to express energy. 1 kWh is the amount of energy consumed by an electrical gadget in one hour at the r..

Commercial Unit of Electrical Energy - Kilowatt - hour is the commercial unit of electrical energy. We have seen that power is the rate of energy consumed or delivered. If 1 joule of energy is used per second, we say that energy is used at the rate of 1 watt...

Commercial Unit of Electrical Energy - The unit 'watt' is very small. Therefore, in actual practice we use a much larger unit called 'kilowatt'. It is equal to 1000 watts. Since electrical energy is the product of power and time, watt hour (W h) can also be c..

Kilowatt - hour is the commercial unit of electrical energy. We have seen that power is the rate of energy consumed or delivered. If 1 joule of energy is used per second, we say that energy is used at the rate of 1 watt. In other words, if energy is used at the rate of 1 watt, t..

What is the length of AC, if the side of each small square is 1 unit? => 6√2 units or 6 units or 8√2 units or 4√2 units..

Find the length of AC in the dot paper, if the distance between each dot is one unit. => 10 5 units or 8 5 units or 5 5 units or 8 units..

Therefore the non-resistive of a coil to a.c. due to the varying magnetic field is called capacitive reactance Xc. Unit of Xc is also Ohm The current leads the EMF by 90 o and the phasor diagram is: For DC, Xc becomes infinite and hence, capacitance block DC flowing through i..

AC Circuit Containing Pure Inductance only - Let an AC source be connected across a pure inductive element. If the alternating current I = I o sin w t flows through it. Then According to Kirchhoff's Law E = E o cos w t ..

ABCD is a parallelogram of area 52 square units. The two diagonals AC and BD intersect each other at point O. Find the area of the region colored red. => 39 square units or 19.5 square units or 13 square units or 78 square units..
