A battery has a variable EMF E depending on the amount of electrochemical energy stored in it, U : `E=E_0=[V/V_0]^(1/3)` , where`E_0` is the EMF of the battery when it has the maximum possible energy, `V_0` , stored in it. The internal resistance of the battery is negligible. The battery, with energy stored in it, is connected with a resistance R and the switch is closed at . Choose the correct option(s):
