Question

В гирлянде 100 одинаковых лампочек, соединённых последовательно. Чему равно напряжение на одной лампочке, если гирлянда находится под напряжением 220 В?

Answer 1

Calculation of Voltage on One Bulb in a Series Circuit

In a series circuit, the total voltage is divided equally among all the components connected in series. Therefore, to calculate the voltage on one bulb in a series circuit, we need to divide the total voltage by the number of bulbs.

In this case, we have a series circuit with 100 identical bulbs and a total voltage of 220 V. To find the voltage on one bulb, we divide the total voltage by the number of bulbs:

Voltage on one bulb = Total voltage / Number of bulbs

Voltage on one bulb = 220 V / 100 bulbs

Voltage on one bulb = 2.2 V

Therefore, the voltage on one bulb in the given series circuit is 2.2 V.
