It is a safety procedure in industries that lock dangerous machines and ensure that there is no operation until maintenance or repairs have been made.
The term used is called “Goods”
Most thunderstorms form by a cycle that has three stages: the cumulus stage, mature stage, and dissipating stage. The sun heats the Earth's surface during the day. The heat on the surface and warms the air around it. Since warm air is lighter than cool air, it starts to rise (known as an updraft)
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.
