*urgent* can anyone me with question 3b ? ?

question: the current in a small bulb is 0.20a
a) what is the total electric charge which passes a point in the circuit in 12min
b) how many electrons pass this point in this time

there is a piece of information at the beginning of the test also saying:
charge on an electron= 1.6x10 power minus 19
idk if that will

also explain with working

A) 144 C

The electric current is defined as

where

q is the charge passing a given point of the circuit in a given time

t is the time interval considered

For this bulb, we know that:

I = 0.20 A is the current

is the time considered

Therefore, the amount of charge passing the point in the circuit in this time is

B) electrons

The charge of one electron is

And the total charge passing through the point in the circuit in 12 min is

So the total charge can be written as

where

n is the number of electrons passing that point  of the circuit in 12 min

So, solving for n,

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

it's a b and
