Is it possible to sequentially connect two lamps of the same power, designed for 110 V each, to a 220 V network?
| September 3, 2021 | education
U = 220 V.
N1 = N2.
U1 = U2 = 110 V.
With a series connection of light bulbs, the voltage in the circuit U is the sum of the voltages on each light bulb: U = U1 + U2.
U1 + U2 = 110 V + 110 V = 220 V.
We see that the total voltage U1 + U2 = 110 V does not exceed the voltage in the circuit, so the bulbs can be switched on in series.
Answer: light bulbs can be connected in series to the network.
