WebThis barrier to the flow of electric current offered by a substance is therefore called electrical resistance. 1. The electrical resistance of the material is directly proportional to the length of the material. 2. The electrical resistance of the material is inversely proportional to the material's cross-sectional area. do you need a permit to install an awningWebIn a parallel combination, the equivalent resistance is lesser than the least of all the resistances. If two resistances R 1 and R 2 are connected in parallel then. If there are n resistors each of resistance R – Let RS be the resultant resistance of series combination and Rp be the resultant resistance of parallel combination. Then, RS = nR. do you need a permit to hike colchuck lakeWebApr 7, 2024 · Electric Potential difference. a) Water level in A is greater than water level in B. b) Pressure exerted by A is greater than pressure exerted by B.
