Question

Сила короткого замыкания источника тока 10 А, его ЭДС 4,5 В. Чему равно внутреннее сопротивление источника?

Answer 1

Дано

I max=10A

E=4.5B

r ?

I max=E/r  r=E/I max=4.5/10=0.45Om

Answer 2

I=E\r, где Е-эдс. ну и все. Отсюда r=0.45 ом

Answer 3

Calculating the Internal Resistance of the Source

To calculate the internal resistance of the source, we can use the formula:

Internal resistance (r) = (EMF - Ux) / I

Where: - EMF = Electromotive force (voltage of the source) - Ux = Voltage across the load - I = Current

Given: - EMF = 4.5 V - I = 10 A

Using the given values, we can calculate the internal resistance of the source.

Internal resistance (r) = (4.5 V - Ux) / 10 A

Calculation

Internal resistance (r) = (4.5 V - Ux) / 10 A

Based on the provided information, the value of Ux is not explicitly given in the search results. Therefore, without the specific value of Ux, it's not possible to calculate the exact internal resistance of the source using the provided information.
