Question

К сети 220в последовательно подключены две лампы сопротивлением 220ом каждая.найти силу тока в каждой лампе.

Answer 1

Сила тока на лампах одинаковая и равна I=U/(R1+R2)=220/440=0,5 A

Answer 2

Calculating Current in Each Lamp

To find the current in each lamp, we can use Ohm's law, which states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). The formula for Ohm's law is:

I = V / R

In this case, the lamps are connected in series to a 220V power supply, and each lamp has a resistance of 220Ω. Using Ohm's law, we can calculate the current flowing through each lamp.

The formula for calculating the current (I) in each lamp is:

I = V / R

Where: - I = current in the lamp - V = voltage across the lamp (220V in this case) - R = resistance of the lamp (220Ω in this case)

Substituting the values, we get:

I = 220V / 220Ω = 1A

So, the current flowing through each lamp is 1 ampere.
