Calculate:i. total resistance andii. total current in the following circuit.R1 = 3 Ω, R2 = 6 Ω, R3 = 5 Ω, V = 14 V

Answer»

i. R₁ and R₂ are connected in parallel. This combination (R_P) is connected in series with R₃.

∴ Total resistance, R_T = R_P + R₃

R_P = \(\frac{R_1R_2}{R_1+R_2}=\frac{3\times6}{3+6}\) = 2 Ω

∴ R_T = 2 + 5 = 7 Ω

ii. Total current: I = \(\frac{V}{R_T}=\frac{14}{7}\) = 2 A
