The number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.
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
[tex]\rm I = \dfrac{30}{20} = 1.5 \;C/s[/tex]
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
[tex]\dfrac{1.5}{1.6e+ ^2^1} = 0.9375e+^1^9[/tex]
In 10 minutes
[tex]0.9375e+^1^9 \times 60 \times 10 = 5.625e+^2^1[/tex]
Thus, the number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.
