Question

Дві електричні лампочки з однаковим опором 10 Ом з'єднані послідовно, визначте загальний опір.​

Answer 1

Ответ:

R = 20 Ом

Объяснение:

Дано:

$R_{L} =$ 10 Ом

Знайти:

$R \ - \ ?$

-------------------------------

Розв'язання:

При послідовному з'єднанні:

$R = R_{1} + R_{2} + \ldots + R_{n}$

$R = R_{1} + R_{2} = R_{L} + R_{L} = 2R_{L}$

$R =$ 2 * 10 Ом = 20 Ом

Відповідь: R = 20 Ом.

Answer 2

Calculating the Total Resistance of Two Electric Bulbs Connected in Series

When two electric bulbs with the same resistance of 10 Ohms are connected in series, the total resistance can be calculated using the formula for resistors in series.

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

R_total = R1 + R2 + ... + Rn

Where R1, R2, ... Rn are the individual resistances.

In this case, with two electric bulbs (R1 and R2) each having a resistance of 10 Ohms, the total resistance (R_total) can be calculated as:

R_total = R1 + R2 = 10 Ohms + 10 Ohms = 20 Ohms

Therefore, the total resistance of the two electric bulbs connected in series is 20 Ohms. This means that the combined resistance of the two bulbs is 20 Ohms when they are connected in series.
