  41. What power is used if a resistance of 100 ohms has a current of 0.1 amps flowing through it?

  42. What power is used if a resistance of 100 ohms has a current of 0.1 amps flowing through it? Remember, P= IV ; or watts = amperes X volts Here we must first determine the volts before we can solve for watts. From Ohm’s Law, we know that V= IR ; or volts = amperes X ohms Thus, in this case, volts = 0.1 amps X 100 ohms = 10 volts. Substituting this value in our power equation above gives: watts = 0.1 amperes X 10 volts = 1 watt

  44. What is the power used in a device if the resistance is 100 ohms and the voltage across it is 4V? Remember, P= IV ; or watts = amperes X volts Here we must first determine the amperes before we can solve for watts. From Ohm’s Law, we know that V= IR ; or volts = amperes X ohms. Rearranging this equation gives: amperes = volts ohms Thus, in this case, amperes = 4 volts = .04 amperes 100 ohms Substituting this value in our power equation above gives: watts = 0.04 amperes X 4 volts = .16 watts
