calculate EMF of Battery

Asked by c_hockland in Math & Science Questions

Tags: emf, calculate, battery

when an external resistor R1=14 is connected to the terminals of the battery , a current of I=6 flows through the resistor. when an external resistor of R=64.4 is connected instead, the current is 2. Calculate the
emf of the battery and the internal resistance of the battery

solution that i tried:

for emf :  emf = Vab = IR  6*14

internal resistance should be  Vab= Emf-I*R and solve for R ,

am i right??Start Free Trial
