why does the lamp bright when it is connected to the AC supply
A lamp will only operate at its rated power at its rated voltage. So if you connected a 230-V lamp to a 110-V supply, its brightness would be very low. It does not matter whether the supply is AC or DC; a lamp would have the same brilliance at 230 V (AC) as at 230 V (DC).As a rule of thumb for fixed-value resistances, a 10% drop in voltage results in a 19% drop in power.
It's not really useful at all, unless you are an electrician or are studying electricity at school or college. After all, who cares how the lamp is connected -all most people are interested in, is whether the lamp is bright enough for its purpose.
A lamp or light fitting will light up if connected to either Alternating Current (AC), or Direct Current (DC). AC is from the mains, and DC is from a battery. So it depends on the construction and components used to construct the lamp as to which electrical source you use.
If the patient is suffering from lack of bright sunshine in the winter, then a heat lamp or a bright sun lamp could be provided.
The term plus or minus is usually a term designated to DC Sources. The terminology for AC systems in laymen terms is neutral and "hot". On a lamp socket, for safety reasons the lamp shell should be connected to the neutral wire and the "hot' wire connected to the bottom centre contact point. In North America this is done automatically by connecting the white wire the silver coloured terminal and the black coloured wire to the brass coloured terminal. If the lamp socket is on a table lamp and it is wired with lamp cable, the neutral is identified by the raised rib on one of the two wires.
To operate at its rated power, a lamp must be subject to its rated voltage (the supply voltage). As each branch of a parallel circuit is subject to the same voltage (the supply voltage), each lamp will operate at its rated power.
Bright light.
bright,colourful, maybe something to describe its pattern portable light, lamp, kerosene lamp, oil lamp
The strongest outdoor lamp would be either an LED lamp, or a halogen lamp. They both have really bright lighting and their bulbs can last for a very long time.
In a series circuit, the total resistance is the sum of the individual resistances. So, the total resistance of the 3.0 lamp and 6.0 lamp connected in series would be 3.0 + 6.0 = 9.0 ohms.
The purpose of a lamp chain is to control the on/off function of a lamp. It is typically connected to the lamp socket and allows the user to easily turn the lamp on or off by pulling or pushing the chain. The chain is connected to a switch mechanism inside the lamp that completes or interrupts the electrical circuit, controlling the flow of electricity to the light bulb.
When two light bulbs are connected in series , there is voltage drop which causes the second lamp to dimAnswerWhen two lamps are connected in series, neither lamp will be subject to its rated voltage and, so, each lamp will be dim. Surprisingly, perhaps, the lamp with the higher power will be dimmer than the lamp with the lower power!
