The power P in watts which is dissipated in an electric circuit with resistance R is known
Question:
The power P in watts which is dissipated in an electric circuit with resistance R is known to be given by P = I2 R, where I is current in amperes and R is a fixed constant at 50 ohms. However, I is a random variable with μ1 = 15 amperes and σ21 = 0.03 amperes 2. Give numerical approximations to the mean and variance of the power P.
