The current in an alternating circuit varies in intensity with time. If "I" represents the intensity of the current and "t" represents time, then the relationship between "I" and "t" is given by:
I=20sin(120pi*t)
where I is measured in amperes and t is measured in seconds. Find the maximum value of I and the time it takes for I to go through one complete cycle

i suppose we differentiate here ?
OpenStudy (anonymous):
I don't know
OpenStudy (earthcitizen):
we find the higher derivatives of \[di/dt, d ^{2}i/dt ^{2}\]
OpenStudy (anonymous):
Maximum value of sine function is 1
hence maximum current is 20A
OpenStudy (anonymous):
max value of of I is 20; complete cycle is 1/60 sec
