#8 - (Frequency =1/period). An electric current alternates with a frequency of 60 cycles per second. This is called quite aptly alternating current and is the type of electrical system we have in our homes and offices in the United States. Suppose that at t=0.01 seconds, the current is at its maximum of I=5 amperes. If the current varies sinusoidally over time, write an expression for I amperes as a function of t in seconds. What is the current at t=0.3 seconds?
