K= direct current constant – use12.9for copper conductors and21.2for aluminum conductors. This is equal to the resistance of a conductor that is one thousand circular mils in area and one thousand feet in length. I= current in amps
Current is measured inamps, symbolized by the letter “I”. Resistance is measured inohms, symbolized by the letter “R”. Ohm’s Law: E = IR ; I = E/R ; R = E/I RELATED WORKSHEETS: Ohm’s Law Worksheet Ohm’s Law Practice Worksheet With Answers ...
Calculate the resistance, in Ohms, by dividing the voltage by the current. Ohms law states that voltage = current x resistance, so by rearranging the formula resistance = voltage / current. Using the example in Step 1, with a voltage of 50 volts and a current of 2 amps, the resistance ...
