Question

При электросварке сила тока достигает 200А. какой электрический заряд проходит через поперечное сечение электрода за 5 мин?

Answer 1

I=200 A

t=5 м=300 с

q=?

 

q=I*t

q=200*300

q=60000 Кл=60 кКл

Answer 2

q=It;   q=200*300;   q=60000Кл 

Answer 3

Calculation of Electric Charge

To calculate the electric charge passing through the cross-sectional area of the electrode during the welding process, we need to know the current and the time. In this case, the current is given as 200A, and the time is given as 5 minutes.

The electric charge passing through a conductor can be calculated using the formula:

Q = I * t

Where: - Q is the electric charge (in coulombs) - I is the current (in amperes) - t is the time (in seconds)

To convert the given time of 5 minutes to seconds, we multiply it by 60:

t = 5 minutes * 60 seconds/minute = 300 seconds

Now we can substitute the values into the formula:

Q = 200A * 300s = 60,000 coulombs

Therefore, the electric charge passing through the cross-sectional area of the electrode during the 5-minute welding process is 60,000 coulombs.
