-t/1000 1) An empty battery is charged from t = 0 with a constant voltage of v(t) = 7.2 V and a current that decays exponentially as i(t) = 100e mA for t> 0 as it charges, where t is measured in seconds. How much charge is transferred during the first 5 minutes of charging? [4 pts] b. How much energy is transferred during the first 5 minutes of charging? [3 pts] What is the total energy storage capacity of the battery? [3 pts] a. C. a. 2) Consider the circuit diagram below: Calculate and draw the Thevenin equivalent between terminals A and B. b. Calculate and draw the Norton equivalent between terminals A and B. If a 102 resistor is attached between A and B, what is the resulting VAB?
