WebJan 25, 2024 · Solved Examples. Q.1. Three resistors of values 2Ω,4Ω2Ω,4Ω, and 6Ω6Ω are connected in parallel. Find the equivalent resistance of the combination of resistors. Ans: The equivalent resistance, in the case of parallel connection, is equal to the inverse of the sum of the reciprocals of all resistances. Q.2. WebApr 8, 2024 · Current flowing from the cell is, I = 0.37 A. The relationship between emf of a cell, potential difference, current & internal resistance is given as, e = V + Ir. After rearranging the equation we can write; e – V = Ir. (e – V)/I = r. Therefore we see that r = (3.0 – 2.8)/0.37 = 0.54 Ohm. Now due to the Internal Resistance which is of the ...
