(i) Draw the pattern of the magnetic field lines for the two parallel straight conductors carrying current of same magnitude 'I' in opposite directions as shown. Show the direction of magnetic field at a point O which is equidistant from the two conductors. (Consider that the conductors are inserted normal to the plane of a rectangular cardboard.) (ii) In our houses we receive A.C. electric power of 220 V. In electric iron or electric heater cables having three wires with insulation of three different colours – red, black and green are used to draw current from the mains.
- (a)What are these three different wires called? Name them colourwise.
- (b)What is the potential difference between the red wire and the black wire?
- (c)What is the role of the wire with green insulation in case of accidental leakage of electric current to the metallic body of an electrical appliance?
