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.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
