Two resistors A and B are 60,000 and 40,000 (omega sign) respectively and are in series across a constant power supply of 100V. A 10,000 (omega sign) is connected across B. What is the current flowing in the circuit? What amount of current is flowing in each of the 3 resistors? ( Please show your work clearly so I can understand)
