Explain Ohm's Law, and use Ohm's Law to calculate the number of watts used for an electrode operating at 18 volts and 90 amps.
What will be an ideal response?
Ohm's Law states that the watts used in a circuit are determined by multiplying the voltage times the amperage. For example, a 1/8-in.-diameter E6011 electrode will operate at 18 volts and 90 amperes. The total watts used would be
W = V × A
W = 18 × 90
W = 1620 watts of power

Consider a perfectly insulated (no heat loss from the skin) 80-L electric water heater set at 60°C. Observing that one tank of hot water is sufficient to meet the hot water needs of a family for an entire day, someone suggests using a timer to heat the water once a day to the set temperature and then turning it off to save energy and money. Do you think the family should take this advice and invest in a timer? Assume there is a single tariff for electricity for all hours of the day.
