    Mean of Current I with Random variable of R

    Hi all, I am new to probability and not so good at it, So please bear with me :) If a voltage e is connected across a resistor whose resistance is random variable R, and uniformly distributed between a and b, I needed to find the Mean of current "I" given by "I = e/R" My question...
