1.6 inches = 1.6 inches x 1,000 mils per inch = 1,600 mils 0.25 inch = 0.25 inch x 1,000 mils per inch = 250 mils Area = 1,600 x 250 = 400,000 square mils
A coil having large number of turns of fine wire is wound on the middle limb of the shunt magnet. This coil is known as pressure or voltage coil and is connected across the supply mains. The voltage coil produces a high ratio of inductance to resistance.
In this type of tariff, The total charge is divided into two components: fixed charges and running charges. The fixed charges depend upon the number of units consumed by the consumer. It can be expressed as Total Cost = [A (kW) + B (kWh)] Rs. A = charge per kW of max demand (A is a constant which when multiplied with max demand (kW) gives the total fixed costs.) B = charge per kWh of energy consumed (B is a constant which when multiplied with units consumed (kWh), gives total running charges.)
