Question

проводники сопротивление 1 и 2 Ом соединены последовательно. Найти силу тока в первом проводнике, если напряжение на втором проводнике равно 3 В

Answer 1

проводники сопротивление R1=1 и R2=2 Ом  соединены последовательно. Найти силу тока в первом проводнике, если напряжение на втором проводнике  равно U2=3  В  I- ?

I=U2/R2=3/2=1,5 А
При последовательном соединении I1=I2= 1,5 А - ответ

Answer 2

Calculation of Current in the First Conductor

To find the current in the first conductor, we need to apply Ohm's Law and the concept of series circuits. In a series circuit, the current remains the same throughout all the components.

Given: - Resistance of the first conductor (R1) = 1 Ω - Resistance of the second conductor (R2) = 2 Ω - Voltage across the second conductor (V2) = 3 V

We can use Ohm's Law to find the current in the second conductor (I2) using the formula:

V = I * R

Rearranging the formula, we have:

I = V / R

Substituting the values, we get:

I2 = V2 / R2 = 3 V / 2 Ω = 1.5 A Since the current remains the same in a series circuit, the current in the first conductor (I1) will also be 1.5 A.

Therefore, the current in the first conductor is 1.5 A.
