Question

Резистори з опором 5 ом і 10 ом з'єднані послідовно.Чому дорівнює їх загальний опір?Яким буде опір цих же резисторів, якщо їх з'єднати паралельно ​

Answer 1

Ответ:

Оскільки це послідовне з'єднання то R=R1+R2

тому R=15

Answer 2

Series Connection of Resistors

When resistors are connected in series, their resistances add up to give the total resistance of the circuit. In this case, we have two resistors with resistances of 5 ohms and 10 ohms connected in series. To find the total resistance, we simply add the individual resistances together.

The total resistance (R_total) of resistors connected in series is given by the formula:

R_total = R1 + R2 + R3 + ...

In this case, the total resistance (R_total) of the two resistors connected in series is:

R_total = 5 ohms + 10 ohms = 15 ohms [[1]].

Parallel Connection of Resistors

When resistors are connected in parallel, the total resistance is calculated differently. In a parallel connection, the reciprocal of the total resistance is equal to the sum of the reciprocals of the individual resistances.

The formula for calculating the total resistance (R_total) of resistors connected in parallel is:

1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

In this case, if we connect the two resistors (5 ohms and 10 ohms) in parallel, the total resistance (R_total) can be calculated as follows:

1/R_total = 1/5 ohms + 1/10 ohms

Simplifying the equation:

1/R_total = 2/10 ohms + 1/10 ohms

1/R_total = 3/10 ohms

Taking the reciprocal of both sides:

R_total = 10/3 ohms ≈ 3.33 ohms [[2]].

So, when the two resistors with resistances of 5 ohms and 10 ohms are connected in parallel, the total resistance is approximately 3.33 ohms.
