Question

Елочная гирлянда состоит из 20 одинаковых лампочек соединена последовательно и подключена к напряжению 220 в.чему равно напряжение на каждой лампочке ?(C решением пожалуйста)

Answer 1

Calculation of Voltage across Each Bulb in a Series Circuit

To determine the voltage across each bulb in a series circuit, we need to consider the total voltage supplied and the number of bulbs connected in series.

In this case, we have a series circuit with 20 identical bulbs connected in series and powered by a voltage of 220 V.

In a series circuit, the total voltage is divided equally among the components. Therefore, the voltage across each bulb will be the total voltage divided by the number of bulbs.

To calculate the voltage across each bulb, we can use the following formula:

Voltage across each bulb = Total voltage / Number of bulbs

Substituting the given values:

Voltage across each bulb = 220 V / 20 bulbs

Calculating the result:

Voltage across each bulb = 11 V

Therefore, the voltage across each bulb in the given scenario is 11 volts.
