Answer 1

answer is 2 coloumb.

Answer 2

Answer:

A current of 2 A flows through a 10ohm resistor for 20 minutes. The amount of charge that flows through the resistor in one second is $48000 \ J$

Explanation:

• Let R be the resistance, A be the current flowing and t be the time of flow of current.

• Let H be the heat produced due to this flow of current

        It is given by the expression,

       $H = I^{2}R t$       ...(1)

In the question, it is given that,

$R =10\Omega$         $I = 2 A$         $t = 20 min = 20\times 60 = 1200\ s$

substitute these values into equation(1)

we get,

$H = 2^{2}\times 10\times 1200=48000 J$
