So we're supposed to find the time. It'll voltage in the first part. So terminal voltage is given by M f minus I the current it can supply times the intel new distance am If it's 1.54 as we are given minus the current we are using from the battery is to amperes And the resistance is 0.1. The internal the distances point What? So this will be equal to 1.3 for a vote? Answer On the numerous page is rock. Now for the part B, we are asked to find how much power electrical power does the sell produce power is equal to enough times the current This is equal to three times so sorry 1.54 times, which is the potential signs The current two This would be equal to 3.8 What, in part seeing you are asked how much off it is available to the load as we start in the first part Actual terminal voltages 1.34 fold. So power for the lower will be equal to V Time site which is 1.34 times two. This is equal to 2.68 What? So this instant power available to the load? Thank you
