With a current of 1 Ampere, work of 10 J. was carried out on the section of the circle. Find the time for performing work with a voltage of 4 volts?
These tasks: I (current strength in the section of the circle) = 1 A; A (work carried out by the current) = 10 J; U (operating voltage) = 4 V.
To calculate the time for the current to perform work, we apply the Joule-Lenz law: Q = I * U * t, whence t = Q / (I * U).
Calculation: t = 10 / (1 * 4) = 2.5 s.
Answer: The current carried out a work of 10 J in 2.5 seconds.
