A battery of a computer has an emf of 12 Volts. The computer uses l=360mA while running.
If the computer runs out of battery in t=7.3 hours, what is the energy stored in the
battery?(answer will be answered in units of Wh....note: in order to transform Joule into Wh, which means
Watt hours, just divide the number obtained in Joule by 3600-s)
What is the maximum power in W that can be generated from an 18 V emf using any combination of a 6.0 Q resistor, and 9.0 Q resistor?
Find the value of the unknown emf shown in the figure, if the current I=1.1 A.
