How many electrons pass through a 20-ohms resistor in 10 min if there is a potential drop of 30 volts across it?
tangare [24]

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

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

In 10 minutes

0.9375e+^1^9 \times 60 \times 10 = 5.625e+^2^1

Thus, the number of electrons passes through 20 ohms resistor in 10  minutes is 5.625e+21.
