Chapter 4.5, Problem 84E

(a)

To determine

To calculate: The average current in $0\le t\le \frac{1}{60}$, where oscillating current of a circuit is given by $I=2\sin \left(60\pi t\right)+\cos \left(120\pi t\right)$

(b)

To determine

To calculate: The average current in $0\le t\le \frac{1}{240}$, where oscillating current of a circuit is given by $I=2\sin \left(60\pi t\right)+\cos \left(120\pi t\right)$

(c)

To determine

To calculate: The average current in $0\le t\le \frac{1}{30}$, where oscillating current of a circuit is given by $I=2\sin \left(60\pi t\right)+\cos \left(120\pi t\right)$
