Two conducting wires x and y of same diameter


Asked by admin @ in Physics viewed by 429 People


two conducting wires x and y such that diameter of x is half that of y and number density of electron in y is three times that in x are joined in series across a battery. find the ratio of drift velocity of electrons in wire x to y

Answered by admin @



Answer:  2:1v

Explanation:  No. density of x =2y and no. density of y is y. According to question both wires have same diameter and joined in series. Therefore, both have same area, charge and current. Vdy\vdx = 2y\y Vdy\vdx =2:1v
