A resitor of unknown resistance and a 35-omega resistor are connected across a 120-V emf device in such a way that an 11-A current flows. What is the value of the unknown reisistance?

  • Physics -

    No more than 120/35 = 3.43 A could flow if the resistors were in series. Theretore I mus assume that they are in parallel and that 11-3.43 = 7.57 A flows through the unknown resistor. Use that fact and the 120 V applied voltage to get its resistance, R = V/I = 15.85 ohms
