Webpotential difference is measured in volts (V) current is measured in amps (A) Example A current flows through a 2.0 A electric drill at a potential difference of 230 V. Calculate the … WebResistance + equation The potential difference required to drive a current through a component R = V/I resistance (ohms) = potential diff. (V) / current (A) Describe the relationship between current moving through a resistor and the potential difference Current moving through a resistor is directly proportional to the potential difference WebThe units of potential difference are Volts (\text{V}) and it can be measured using a voltmeter. A voltmeter must be connected in parallel with the component for which you … red cross of northern nevada
