The number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.
<h3>What is a resistor?</h3>
In an electronic circuit, a resistor is an electrical component that limits or regulates the flow of electrical current.
Given, the resistance is 20 ohms.
The potential difference is 30 volts
Time is 10 minute
By the formula of current
![\rm I = \dfrac{30}{20} = 1.5 \;C/s](https://tex.z-dn.net/?f=%5Crm%20I%20%3D%20%5Cdfrac%7B30%7D%7B20%7D%20%3D%201.5%20%5C%3BC%2Fs)
The charge flowing through the resistor is 1.5 C/s
1 electron charge is 1.6e+19
Now, the number of electrons passing through a 20 ohms resistor is
![\dfrac{1.5}{1.6e+ ^2^1} = 0.9375e+^1^9](https://tex.z-dn.net/?f=%5Cdfrac%7B1.5%7D%7B1.6e%2B%20%5E2%5E1%7D%20%3D%200.9375e%2B%5E1%5E9)
In 10 minutes
![0.9375e+^1^9 \times 60 \times 10 = 5.625e+^2^1](https://tex.z-dn.net/?f=0.9375e%2B%5E1%5E9%20%5Ctimes%2060%20%5Ctimes%2010%20%3D%205.625e%2B%5E2%5E1)
Thus, the number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.

Originally a small country on the southeastern shores of the Baltic Sea, it became a major European power, covering much of modern northeastern Germany and Poland, under Frederick the Great. After the Franco-Prussian War of 1870–71, it became the center of Bismarck's new German Empire, but was abolished following Germany's defeat in World War I.</span>
