Series and Parallel Circuits Computer Lab

Find the resistance that must be put in series with a resistor of 400 ( such that, when 120 V is applied across the combination, the current in the circuit will be 0.010 A. A 10 ( resistor, a 11 ( resistor and a 39 ( resistor are connected in series across a potential difference of 120 V. Calculate the voltage drop across the 10 ( resistor. ................
