Question

a potential difference of 10V is applied across a conductor of resistance 1Kohm find the number of electrons flowing through the conductor in 5 minutes​

Answer 1

Answer:

Explanation:q = I × t

From Ohm's law, V=IR

I=\dfrac{V}{R}

So, q=\dfrac{V\times t}{R}

q=\dfrac{10\times 300}{1000}

q = 3 C

Also, q = n e

n is number of electrons

n=\dfrac{q}{e}

n=\dfrac{3}{1.6\times 10^{-19}}

n=1.87\times 10^{19}

Hence, the number of electrons flowing through the conductor in 300 s is 1.87 × 10¹⁹.
