A resistor of 40 ohms is in series with two resistors A and B in parallel. The resistance of A is 100 ohms. The entire series parallel circuit is connected across a 120 Volt supply. Determine (a) Ohms to which resistor B must be adjusted in order that it will take current of 0.48 A; (b) current in resistor A; (c) voltage across resistors A and B
