The rated voltage of a color lamp is 36V. It needs to be connected to the circuit of 220V. How many such bulbs are connected in series to work normally Why is 220 divided by 36 equal to 7? Isn't 36 multiplied by 7 more than 220 V

The rated voltage of a color lamp is 36V. It needs to be connected to the circuit of 220V. How many such bulbs are connected in series to work normally Why is 220 divided by 36 equal to 7? Isn't 36 multiplied by 7 more than 220 V

220/7=6.111111
When connecting six, the voltage on one lamp is 220 / 6 = 36.66667, which is more than 36V, abnormal
When seven are connected, the voltage of one lamp is 220 / 7 = 31.426, which is less than 36V
As for 36 * 7 > 220, this algorithm is wrong, because the voltage on the lamp is not necessarily 36V,
The rated voltage of 36V means that it cannot exceed 36V

The normal working voltage of a kind of festival lantern is 6.3V. If you want to connect this kind of lantern in the home circuit (the power supply voltage is 220V) to decorate the room, you need at least one connection

35 in series

How much is the voltage of the festival's small color lamp? Why can such a small bulb be directly plugged into the 220 V power supply?

The working voltage of the festival lights is different, but far lower than 220 v
Festival lights are used in series, which can divide voltage. For example, 20 Festival lights are connected in series in a 220 V circuit, and the voltage at both ends of each small light is 220 V / 20 = 11 V, so it will not burn out

A festival lantern called Mantianxing, a group of 110 small lanterns in series, they are connected to the voltage of 220 V, the voltage at both ends of each small lantern?
Don't answer if you can't

If you want to calculate the voltage: 220 times the power factor (generally between 0.43-0.75), and then divide by the number, the number is the voltage at both ends!
