Question

Внутреннее сопротивление генератора тока равно 0.60 ом. При замыкание на внешнее сопротивление 6,0 ом напряжение на его зажима становится равным 120в. Определитесилу тока в цепи и э.д.с генератора

Answer 1

Ответ:

ЭДС=120В; I=18,18А

Объяснение:

ЭДС=U=120В

I=ЭДС/R+r=120/0,6+6=18,18 А

Answer 2

Calculation of Current and EMF of the Generator

To determine the current and electromotive force (EMF) of the generator, we can use Ohm's Law and the formula for calculating power.

Given information: - Internal resistance of the generator (R_internal) = 0.60 Ω - External resistance (R_external) = 6.0 Ω - Voltage across the terminals of the generator when connected to the external resistance (V_terminal) = 120 V

Using Ohm's Law, we can calculate the current (I) in the circuit: I = V_terminal / (R_internal + R_external)

Substituting the given values: I = 120 V / (0.60 Ω + 6.0 Ω)

Calculating the current: I ≈ 120 V / 6.60 Ω ≈ 18.18 A

To calculate the electromotive force (EMF) of the generator, we can use the formula for power: P = I * V_terminal

Rearranging the formula to solve for EMF (E): E = P / I

Substituting the given values: E = (I * V_terminal) / I

Simplifying the equation: E = V_terminal

Therefore, the electromotive force (EMF) of the generator is equal to the voltage across its terminals when connected to the external resistance, which is 120 V.

In summary, the current in the circuit is approximately 18.18 A, and the electromotive force (EMF) of the generator is 120 V.
