Determine the current strength if the internal resistance is 10 m, the external resistance is 50 m, the current strength is 0.2A.
| April 29, 2021 | education
Initial data: r (internal resistance) = 10 Ohm, R (external resistance) = 50 Ohm, I (current) = 0.2 A.
The electromotive force of the current source is calculated using the following formula:
Еі = I * (R + r).
Let’s perform the calculation:
Ei = 0.2 * (10 + 50) = 0.2 * 60 = 12 V.
Answer: The electromotive force of the current source is 12 V.
