Two resistances have lengths in the ratio 1:4 and radius 1:2,specific resistances in ratio 3:1. compare their resistances.Solution)Given lengths l1=1 l2=4Given radius r1=1 r2=2 Given specific resistances Ρ(rho)1=3 Ρ2= 1we know the R=Ρl/A R1/R2=3/1.
Can you explain Ohms Law? Ans. If Temperature remains constant then current flow is directly proportional to applied Voltage. I ∝ V, I = V/R (resistance of the conductor)
