Name: Set: Elex 3410 Electrical Industrial Systems Design Lab 2 Tutorial: 1. A 120V electric kettle has a 1500W heating element. a. What is the resistance of that kettle's heating element? b. How much current will it draw at 120V ? 2. If the voltage was only 117.9V, answer the following questions: a. How much current will be drawn by the kettle at this less-than-rated voltage? b. How much power would be dissipated at this lower voltage? 3. What is the maximum allowable cable run distance from the panel to the outlet in the circuit described in number 1? Assume the wire has a resistance of 2.252 per thousand feet or 0.008284 per meter. 4. How could you accommodate this load if it had to be further away than the maximum allowable branch length? 5. A three-wire 120/240V branch circuit has a 1000W portable heater along with two 60W lamps plugged into receptacles connected between H1 and neutral. On the other side of the circuit there are ten 60W lamps and a 200W TV plugged into receptacles connected between H2 and neutral. Determine the current flowing in each of the three conductors. 6. A three-wire circuit has a 120V,1000W electric iron plugged into one side and a 120V, 50W stereo on the other. Unfortunately the neutral wire has become disconnected from the bus at the distribution panel leaving only two conductors; the red and black wires. Calculate the following: a. Total resistance of the circuit. b. Current that will flow through this loop. c. Voltage across each load. d. Power dissipated by each load. 7. In a 120/240V three-wire circuit, why is the neutral wire important
