The power output of the pocket calculator can be found using the formula P = IV, where P is power, I is current, and V is voltage. We can find the current using the formula I = Q/t, where Q is charge and t is time. Thus, I = 4.00 C / 4.00 h = 1.00 A Now, we can plug in the values to find P: P = (1.00 A) x (3.00 V) = 3.00 W Therefore, the power output of the pocket calculator is 3.00 W.
