The 240-volt, 2-amp motor is connected to a three-wire, 120/240-volt system. Connected between the black wire and neutral are four 200-watt, 120-volt lamps and a 120-volt, 1-amp motor. Between the red wire and neutral are three 200-watt, 120-volt lamps, one 1.67-amp motor, and one 120-volt, 1-amp motor. (Round the FINAL answer to two decimal places.)
How many amps flow in the black wire?
