    How Do You Calculate the Radius of a Variable Capacitor's Plates?

    "I = (V/R)e^-0.25 = (10/5000)*(0.7788)=1.5576*10^-4=0.1557*10^-3=0.1557mA" could someone clarify how to get "e^-0.25" from the above equation? and also "0.7788". I don't understand the method that's being used here :-( Thanks
