two 360 OHM resistors are connected in series with a source emf. The voltometer V with internal resistor 6350 is connected across one of the resistors and reads 3.23 V
whats the emf of the source ?

solution that i tried :

I = E / R1+R2 = E / 720

V=I*R thus I = V/R = 6350 / 360 = 17.6
thus E = 17.6 * 720 = 12762

I = 3.23 / 360
E = I * (360+360)
