12.16 A balanced delta-connected load has a phase current IAC = 5⧸−30° A. (a) Determine the three line currents assuming that the circuit operates in the positive phase sequence. (b) Calculate the load impedance if the line voltage is VAB = 440⧸ 0° V.

The mantle is made up of which structural zones?

Which of these metals are magnetic?

Currents in dc transmission lines can be 100 a or higher. some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. for a line that has current 150 a and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? express your answer in teslas and as a percentage of the earth’s magnetic field, which is 0.50 g. is this value cause for worry?
