Question

!Помогите срочно! Нужна схема цепи к этой задаче:Цепь состоит из 2 последовательно соединённых проводников с сопротивлением 10 Ом и 30 Ом. Найдите силу тока в цепи и напряжение на каждом проводнике, если напряжение на концах цепи равна 4 В​

Answer 1

Ответ:

0.1 A

Объяснение:

R1=10 Ом    R2=30 Ом    U=4 B     I=?

===

Rобщ=R1+R2=10+30=40 Ом

I=U/Rобщ=4/40=0.1 A

Circuit Diagram and Calculation

To solve this problem, we need to determine the current flowing through the circuit and the voltage across each resistor. The circuit consists of two resistors connected in series, with resistances of 10 Ω and 30 Ω, respectively. The voltage across the circuit is given as 4 V.

To find the current flowing through the circuit, we can use Ohm's Law, which states that the current (I) flowing through a circuit is equal to the voltage (V) divided by the total resistance (R) of the circuit. In this case, the total resistance is the sum of the resistances of the two resistors.

Let's calculate the current flowing through the circuit:

Step 1: Calculate the total resistance (R) of the circuit by summing the resistances of the two resistors: R = 10 Ω + 30 Ω = 40 Ω

Step 2: Use Ohm's Law to calculate the current (I) flowing through the circuit: I = V / R I = 4 V / 40 Ω I = 0.1 A

Therefore, the current flowing through the circuit is 0.1 A.

To find the voltage across each resistor, we can use Ohm's Law again. Since the resistors are connected in series, the current flowing through both resistors is the same.

Step 3: Calculate the voltage across each resistor: V1 = I * R1 V1 = 0.1 A * 10 Ω V1 = 1 V

V2 = I * R2 V2 = 0.1 A * 30 Ω V2 = 3 V

Therefore, the voltage across the 10 Ω resistor is 1 V, and the voltage across the 30 Ω resistor is 3 V.

Summary

In summary, for the given circuit with two resistors connected in series, with resistances of 10 Ω and 30 Ω, and a voltage of 4 V across the circuit, the following values were calculated:

- The current flowing through the circuit is 0.1 A. - The voltage across the 10 Ω resistor is 1 V. - The voltage across the 30 Ω resistor is 3 V.

Please note that the above calculations are based on the given information and assumptions about the circuit.
