Question

Напруга на виході з генератора 220 В. До споживача потужністю 400 Вт підходить струм 2 А. Визначити , скільки втраченої напруги в лініях електропередач. Срочно допоможіть даю 50 балів

Answer 1

Відповідь:

ΔU=20v

Пояснення:

P=U*I⇒U=P/I⇒400/2=200v    втрати в лінії ΔU дорівнюють різниці напруг генератора і споживача    220-200=20

Answer 2

To determine the amount of voltage loss in the power transmission lines, we need to use Ohm's Law, which states that voltage (V) is equal to the product of current (I) and resistance (R). In this case, the resistance refers to the resistance of the power transmission lines.

Given: - Voltage at the generator output (V) = 220 V - Power of the consumer (P) = 400 W - Current at the consumer (I) = 2 A

To find the resistance (R), we can rearrange Ohm's Law as follows: R = V / I

Substituting the given values: R = 220 V / 2 A R = 110 Ω

Now, we can calculate the voltage loss using Ohm's Law: Voltage Loss = I * R

Substituting the values: Voltage Loss = 2 A * 110 Ω Voltage Loss = 220 V

Therefore, the voltage loss in the power transmission lines is 220 V.

Please note that this calculation assumes that the power transmission lines have a constant resistance and neglects other factors that may affect the voltage loss, such as line length, wire gauge, and power factor.
