Physics

You wire a real battery to a R1 = 42 Ω resistor and find thatthe output voltage between its terminals is V1 = 8.6 V. Youdisconnect it from the first resistor, wire it to a R2 = 720 Ωresistor, and find that its output voltage is V2 = 9.7 V. (a)Determine the current through each resistor. I1 = I2= (b) Find theinternal resistance and emf of the battery. r = Ω e m f = V
