An office workers wants to plug in a 3000 watt 110 volt heater into a standard 15 amp, 110v, electrical outlet. Would this be safe? (Note: w=v times I and W=I^2R
a. No, the resistance can be hazardous and cause fire
b. no, the current required by the heater is approximately 27 amps, which exceeds the capacity of the electrical line
c. Yes, the voltage is too low to do any harm, regardless of the watts or amperes
d. Yes the current required by the heater is only 7 amps, which can be handled by the electrical line
