WebApr 6, 2024 · If the resistance of each edge of a cube shaped wire frame shown in the figure below is R, the resistance between points 1 and 7 is. Updated On. Apr 6, 2024. WebDec 21, 2024 · The Ohm's law formula can be used to calculate the resistance as the quotient of the voltage and current. It can be written as: R = V/I. Where: R - resistance. V - voltage. I - Current. Resistance is expressed in ohms. Both the unit and the rule are named after Georg Ohm - the physicist and inventor of Ohm's law.

WebA wire is also a resistence, and a good example. When we see the electrons bumping into each other and into the atomic nuclei inside the wire, we call that property resistence. Kind of like viscosity in fluids. So if a wire gets longer, it has more chances to bump into something. Also, if a wire gets thicker, an electron will have more chance ...
