How to measure resistance . and Ohm’s Law. The basics of electrical measurement. . Voltage is electrical pressure, which is potential force or the difference in electrical charge between two points. Voltage pushes electrical currents though a wire but not through its insulation.. Comparing shocks from static electricity and electric currents is like comparing apples and oranges, they are similar but quite different at the same time.. Every year many people are injured and sometimes killed from electrocution as even small amounts of electric current can be lethal. . What IS Resistance?. On what will resistance depend?. Electrical Resistance. A measure of how easily charge flows through a material. A . Resistor. is a material of significant resistance that has been placed in an electric circuit in order to control current or voltage.

Department of Electrical and Computer Engineering, Democritus University of Thrace, Xanthi, Greece. Electrons flow due to potential difference. If the potential difference is removed, then electrons stop flowing.. As electrons move, they bump into other atoms, this slows them down and impedes their motion..
