The heating element of a clothes dryer has a resistance of 11 and is connnected to a 240-V electrical outlet. What is the current in the heating element?
If the clothes dryer is run for 5 minutes, how much energy has been delivered to its heating element?
Use Ohm's law to compute the power in the first part and W = (power)*(time)
for ther second part.
Power = (current)*(voltage) = V^2/Resistance
