1) Modern technology has produced a small 1.5-volt alkaline battery with a nominal stored energy of 150 joules. For how many days will it power a calulator that draws a 2-mA current?

2)The current entering the positive terminal of an element is:

i=2sint A for t>=0 and

i=0 for t<0.

The voltage across the element is: v=(2)(dt/dt)

Determine whether the element is active or passive by calucating the energy absorbed by the element.
