Answer 2

Answer:

Equivalent Resistance in Series-Parallel ... (a) Three resistors 2Ω,4Ω and 5Ω are combined in parallel. ... to a battery of emf 20 V and negligible internal resistance, determine the current

(a) For Parallel connection, 1Rp = 1R1 + 1R2 + 1R3 1Rp = 12 + 14 + 15 1Rp = 10 + 5 + 420 Rp = 2019Ω (b) R1 = 2Ω,R2 = 4Ω,R3 = 5Ω I1 = VR1 = 20/2 = ...
