by using partial circuit Ohm's law: R=U/I to measure the resistance value. Use the ammeter to measure the current through the unknown resistor at this voltage, and then calculate the resistance of the unknown resistor. Volt-ampereresistance measurementis...
Controlling impedance (resistance) is almost a given with today’s technology. One day, we are adding a wireless option to a common object and calling it the Internet of Things. The next day, we’re simply keeping up with the competition on processing the code. Days go by and the trend ...
