Question

Calculate 1) total resistance
2) total current in the following circuit
R1 = 3 ohms, R2=6 ohms, R3=5 ohms. V= 14v ​

Answer 1

Explanation:

R1 and R2 are parallel and the combination is in series with R3

so parallel combination resistance is 1/R = (1/3)+(1/6)

R=2 is in series with R3

so total resistance = 7 ohms

We know i=v/r

i=14/7 = 2A

total current = 2A
