Answer:
Yes, there a link between number of bulbs and current drawn from the power pack.
Explanation:
In an Electrical circuit, we have resistors present in that circuit. These resistors can be connected in two ways.
a) Series connection
b) Parallel connection
There is a link or a relationship between number of bulbs and the current drawn from the power pack. This is because the number of bulbs is equivalent to or equal to the number of resistors.
Hence,
a) In a series connection, the link or relationship between the number of bulbs(resistors) is as the number of light bulbs increases, the current in the power pack (circuit) decreases.
b) In a parallel connection, the link or relationship between the number of bulbs(resistors) is as the number of light bulbs increases, the current in the power pack (circuit) increases.
When you pick a book off the floor you are transferring kinetic energy from your hands to the potential energy of the book.
The number of electrons per second is
Explanation:
The current intensity is defined as the amount of electric charge that passes through a given point in a certain time:
where
I is the current
q is the amount of charge
t is the time elapsed
Moreover, assuming that the charge carriers are electrons, the charge can be written as
where
N is the number of electrons
is the charge of one electron
Re-writing the equation,
Here we have:
I = 16 A
t = 1 s
Therefore, the number of electrons is

Answer:
it gets brighter because the volta increases
The electric force (and the gravitational force too) is inversely proportional
to the square of the distance between the objects involved.
In this question, the distance is increased by a factor of (1.25/0.95) .
So the electric force will change by the factor of (0.95/1.25)² .
The new force is
(1.32 N) · (0.95/1.25)² = 0.762... newton (rounded)
