V = IR. Comment. Seven review questions complete the activity. Of course the answer is not just a number, it will be a certain number of Ohms or Volts or Amperes, but wait, there is worse to come - those Ohms Volts or Amperes are very probably going to be kilohms or millivolts or microamperes, right? trailer <]>> startxref 0 %%EOF 125 0 obj<>stream In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third. I = 0.5 amps. electrical heaters are a continuous load so total connected load be 80% of circuit rating, Total allowable wattage = 3600 * 0.8 = 2880 Watts. I = 60/120. (For complaints, use (746 Watts = 1 Horsepower) Power is measured in Watts and is symbolized by the letter P. Power (Watts) equals Energy (joules) divided by time (seconds). By Power Law Practice Problems #3 By Patrick Hoppe. %PDF-1.3 %���� Current Drawn by the bulb = E/I = 100 / 115 = 0.87 Amperes.
