Description : How to solve direct and indirect/inverse variation problem?
Last Answer : .just talk your way thru this ... 1. wire2 is 3 x longer than wire1 .... thus resistance of wire2 has to be 3 x larger than wire1 on the basis of length, alone. 2. wire 2 has a diameter that is 1.5 x larger than wire1 . ... L1/D1^^2 R2 =k * 3*L1/(1.5*D1)^^2 ... you can solve it from there ... ..
