Question

1.A step-up transformer is designed to have an output voltageof 2200 V(rms) when the primary is connected across a 110 V (rms)source. a. If the primary winding has 86 turns, how many turnsare required on the secondary? b. If a load resistor across the secondary draws acurrent of 1.4A, what is the current in the primary, assumingideal conditions? 2.a A long wire carries 100 A current that isperpandicular to the magnetic field lines of a uniform magneticfield of 5mT. At what distance from the wire is the net fieldzero? b. Two long straight wires 20cm apart carry equal valuecurrent I but in opposite direction. Do they attract orrepel? What is the current I if the force per unit lengthbetween them is 5x 10-9N/m? 1.A step-up transformer is designed to have an output voltageof 2200 V(rms) when the primary is connected across a 110 V (rms)source. a.
