Question

В електричному колі послідовно ввімкнено три споживачі опором 50 Ом, 70 Ом і 120 Ом. Визначіть напругу на кожному споживачеві, якщо сила струму в колі 2 А.

Answer 1

Ответ:

100 В 140 В 240 В

Объяснение:

U=I*R

U1=I1*R1

I1=I2=I (з'еднання послiдовне)

U1=50 Ом*2А=100 В

U2=R2*I ; 70 Om* 2A=140 B

U3=R3*I ; 120 Om * 2A =240 B

Вiдповiдь:

U1=100 B

U2=140 B

U3=240 B

Answer 2

Calculation of Voltage across Each Consumer in a Series Circuit

To determine the voltage across each consumer in a series circuit, we need to apply Ohm's Law, which states that the voltage across a resistor is equal to the current flowing through it multiplied by its resistance.

In this case, we have three consumers connected in series with resistances of 50 Ω, 70 Ω, and 120 Ω, respectively. The total current flowing through the circuit is given as 2 A.

To find the voltage across each consumer, we can use the formula:

Voltage (V) = Current (I) × Resistance (R)

Let's calculate the voltage across each consumer:

1. For the consumer with a resistance of 50 Ω: - Voltage (V1) = Current (I) × Resistance (R1) - V1 = 2 A × 50 Ω - V1 = 100 V

2. For the consumer with a resistance of 70 Ω: - Voltage (V2) = Current (I) × Resistance (R2) - V2 = 2 A × 70 Ω - V2 = 140 V

3. For the consumer with a resistance of 120 Ω: - Voltage (V3) = Current (I) × Resistance (R3) - V3 = 2 A × 120 Ω - V3 = 240 V

Therefore, the voltage across each consumer in the given series circuit is as follows: - The voltage across the consumer with a resistance of 50 Ω is 100 V. - The voltage across the consumer with a resistance of 70 Ω is 140 V. - The voltage across the consumer with a resistance of 120 Ω is 240 V.
