What is the equivalent resistance of a circuit that contains three 20.00
resistors connected in parallel with a 12.0 V battery?
A. 30.00
B. 0.600
C. 6.670
D. 60.00

Answer:

C. 6.670

Explanation:

Given data,

The resistance of the resistors, R₁, R₂, R₃ = 20 Ω

The potential difference of the battery, V = 12 V

The formula for resistors connected in parallel,

                                     1/R = 1/R₁ + 1/R₂ + 1/R₃

Substituting the values,

                                       1/R = 1/20 + 1/20 + 1/20

                                          R = 6.67 Ω

Hence, the effective resistance in  parallel connection, R = 6.67 Ω
