A quarter-wave monopole Antenna aligned with the z axis is placed at the origin . An electric field strength of 3x10^-3 is needed at a point described is spherical coordinates as P (2000, π /2,π/4). Neglecting the ohmic loss, How much Power must the Antenna Transmit in order to create the required field Strength at P?
They are separated by a distance equal to their radiusR. They each have N turns and carry equalcurrents I in the same direction. Calculate the field strength if the loops are 11 cm india meter, have 14 turns, and carry a 1.8 A current.
The power consumption of asingle-phase electric load fed from a 120 volt source representedby: P(t) = 100 (1-e-t/10) KW where t is the unit time inhours. Compute the energy consumed by the load over the period of 24 hours.
