Question

Это из источника питания электрической цепи равна 110 Вольт внутреннее сопротивление источника 2 ом амперметр включенный последовательно с нагрузкой показывает 5 ом Чему равно сопротивление нагрузки

Answer 1

(Замечание: Амперметр показывает 5 Ампер!)

По закону Ома для полной цепи:
I = ЭДС / (R+r)

Для упрощения расчетов, сразу подставим данные:

5 = 110 / (R + 2)
R+2 = 100/5
R+2 = 20

R = 20-2 = 18 Ом - сопротивление нагрузки...

Calculation of Load Resistance

To calculate the resistance of the load in the given circuit, we can use Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance.

The circuit consists of a power source with a voltage of 110 volts and an internal resistance of 2 ohms. An ammeter is connected in series with the load, and it shows a resistance of 5 ohms.

Let's denote the resistance of the load as R_load.

According to Ohm's Law, the total current flowing through the circuit can be calculated using the formula:

I_total = V_source / (R_internal + R_load)

where: - I_total is the total current flowing through the circuit, - V_source is the voltage of the power source (110 volts), - R_internal is the internal resistance of the power source (2 ohms), and - R_load is the resistance of the load.

We can rearrange the formula to solve for R_load:

R_load = (V_source / I_total) - R_internal

Now, let's substitute the given values into the formula:

R_load = (110 V / I_total) - 2 Ω

Unfortunately, the provided search snippets do not contain the necessary information to calculate the value of R_load. The snippets are unrelated to the given question.

To provide a more accurate answer, we would need additional information or clarification about the circuit or the specific values of the current or voltage.
