Extracted text: Q.6(a) Explain with reasons, what happens when two wires of negligible masscarrying direct current in the same direction are held close to each other in a dielectric medium. Support your explanation with a suitable diagram (b) Describe the mechanism of conduction of electricity in a metal. Show that the current / carried by a conducing wire of crass- sectional area A is I= nqAva Given that each carrier with a charge q travels with a drift velocity Vd, and n is the number density.
