Parallel circuit resistance equation
WebResistors in parallel circuits When resistors are connected in parallel, we can calculate the total parallel resistance (RT) using the relationship; \ [\frac {1} { { {R_T}}} = \frac {1} { {... WebThe formula for resistors in parallel is, 1/Rp = (1/2) + (1/4)+ (1/6) 1/Rp =11/12 Rp=12/11 Rp = 1.0909Ω Question 2: Calculate total resistance of the given parallel connection; R 1 = 4Ω and R 2 = 5Ω? Solution: Given the value of resistors are, R 1 = 4Ω, R 2 = 5Ω Formula for resistors in parallel is, 1/Rp = (1/4)+ (1/5) 1/Rp = 9/20 Rp = 20/9
