An alkaline battery with an emf of e$=1\mathrm{.}525$V has an internal resistance r$=0\mathrm{.}425$ohms. a multimeter is used to measure a voltage across R$=1\mathrm{.}00$Kilo$-$ohms load resistor connected across terminals of the battery as shown. write an expression for the current that flows through the load resistors. what is the measured terminal voltage
