The current in the wire is 40 m. What electric charge passes through the cross section of the wire in 20 minutes?
| February 18, 2021 | education
To find the value of the charge passed through a given wire, we will use the formula: q = I * t.
Variables: I – current strength (I = 40 A); t – charge passage time (t = 20 min = 1200 s).
Calculation: q = I * t = 40 * 1200 = 48 * 10 ^ 3 Cl = 48 kC.
Answer: A charge equal to 48 kC should have passed through the cross section of a given wire in 20 minutes.
