In a parallel circuit, what effect will adding more resistors to the circuit have? a. the current will increase. b. the current will decrease. c. the current will decrease by a factor proportional to the number of resistors. d. the current is not affected by the number of resistors.

The correct answer is the current will decrease by a factor proportional to the number of resistors.

In a parallel circuit, when all the resistors are in parallel to the power supply, the voltage across all the branches in parallel is the same but the current decreases as we add more load. If each current path P has different resistances, highest current flows through the path which has the least resistance and hence current decreases proportionally.

The current will decrease.

Explanation:

if you add more resistors your will decrease the current its like adding water to fire to control the current.

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.

inverse v=i*r
