​

Answer 1

Explanation:

$\huge{\boxed{10 Ampere}}$

Answer 2

Given:

60 electrons cross through a cross-sectional area per minute.

To find:

Electric current value.

Calculation:

Electric current is defined as the instantaneous rate of charge flow through a defined cross-sectional area.

Putting all the available values in SI unit:

Let current be i :

$\sf{ \therefore \: i = \dfrac{charge}{time} }$

$\sf{ = > \: i = \dfrac{60 \: e}{1 \: min} }$

$\sf{ = > \: i = \dfrac{60 \times 1.6 \times {10}^{ - 19} \: C}{60\: sec} }$

$\sf{ = > \: i = 1.6 \times {10}^{ - 19} \: ampere}$

So, final answer is:

$\boxed{ \large{\sf{ \: i = 1.6 \times {10}^{ - 19} \: ampere}}}$
