The power dissipated in a resistor W is proportional to the square of the voltage V, where r is a constant: W = rV^2 If r = 3, then V (with a very good approximation) is considered a normal random variable with a mean of 6 and a standard deviation of 1. Calculate the probability P(W > 12).

A voltage V is a Gaussian random variable with a mean (μ) equals 1 and a variance (σ^2) equals 2. (a) Find the probability that the voltage V is less than -1.5 (b) Find the pdf of the power dissipated by an R-ohm resistor (P=V^2/R)

Use a variation model to solve for the unknown value. The power in an electric circuit varies jointly as the current and the square of the resistance. If the power is $144 \mathrm{W}$ (watts) when the current is $4 \mathrm{A}$ (amperes) and the resistance is $6 \Omega,$ find the power when the current is $3 \mathrm{A}$ and the resistance is $10 \Omega$
