In the circuit below, the current through B is 1.50 A and the current through C is 0.50 A when A has a resistance of 9 Ω. If you replace A with a 27 Ω resistor, the current through B reduces to 0.75 A and C to 0.25 A. Hint: The voltage drop across the battery (Vbattery) equals the voltage drop accross A plus the voltage drop across B (or C). (Kirchoff-law of voltages).
(a) What is the resistance of B?
(b) What is the resistance of C?
(c) What is the voltage of the battery?
