How many aluminium ions are needed to cross an ammeter if you want a current of 3A?

Physics
1 answer:
Reptile [31]3 years ago
6 0
Assuming that the time needed to cross the ammeter is 1 hour or 3600s, then using coloumb's law,
I x t = F x m / (eq. wt)

Using the given values and formula:
3 x 3600 = 96500 x m / (27/3)

Solving for m,
m = 1.007 g of Al3+

A milliammeter has an internal resistance of 5ohms and
Vikentia [17]

Answer:

Rs = 0.02008 Ω = 20.08 mΩ

Explanation:

The range of an ammeter can be increased by connecting a small shunt resistance to it in a series combination. This shunt resistance can be calculated by the following formula:

Rs = \frac{I_gR_g}{I - I_g}

where,

R_s = value of shunt resistance = ?

I_g = current range of ammeter = 20 mA = 0.02 A

I = Required range of ammeter = 5 A

R_g = Resistance of ammeter = 5 ohms

Therefore,

R_s = \frac{(0.02\ A)(5\ ohms)}{5\ A-0.02\ A}

<u>Rs = 0.02008 Ω = 20.08 mΩ</u>

Why is the light bulb not a closed system?
Nana76 [90]

Answer:An incandescent light bulb gives only energy of the system in the form of heat. ... The roof of a house is stable but it receives energy from the surroundings and transfers energy through it towards lower temperature side which includes no mass transfer. So, it is best considered as closed system.

Ira Lisetskai [31]

Answer:

hello your question is incomplete below is the missing part of the  complete question

which statement best describes Jean-Baptiste Fourier’s influence on Jean-François Champollion? Fourier shared his research about mathematics with Champollion, which aided him in his research. Fourier was the first to introduce Champollion to the hieroglyphs on the Rosetta Stone, which fascinated him. Fourier shared his findings about the Rosetta Stone with Champollion, which helped him in his research. Fourier was the first to introduce Champollion to a variety of languages, which prompted his love of languages.

answer :  Fourier was the first to introduce Champollion to a variety of languages, which prompted his love of languages.

Explanation:

Jean-Baptiste Fourier's influence on Jean-Francois Champollion is that Fourier was the first to introduce Champollion to a variety of languages, which prompted his love of languages. also Fourier was a mathematician  who pleaded on the behalf of Champollion when he was about to be adopted into the military.
