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

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

the part of the wave he is travelling on is the crest

c) up is the direction the magnetic force is acting on the charge.
