Parallel circuit
Series circuit.
The lights are most likely connected in a parallel circuit. In a parallel circuit, each light bulb has its own separate path to the power source. Therefore, if one bulb is missing or burnt out, the other bulbs can still receive power and continue to work.
In series
In a parallel circuit, each light bulb would receive the full voltage of the power source, allowing them to burn brighter compared to a series circuit where the voltage is divided among the bulbs.
This is the case in a series circuit. (like the small Christmas lights.)
When you unscrew one bulb from a series circuit, the electrical path is broken, causing all the other bulbs in that circuit to go out. In a parallel circuit, however, the remaining bulbs continue to function because each one has its own independent path to the power source. Therefore, the outcome depends on the type of circuit configuration.
The type of circuit where bulbs are next to each other is called a series circuit. In a series circuit, the current flows through each component in a single path, making it so that if one bulb goes out, the entire circuit will be broken and all bulbs will turn off. This is in contrast to a parallel circuit, where each component has its own separate path for the current to flow, allowing the other bulbs to stay lit even if one goes out.
It is unclear what type of circuit you are referring to, so I'll give both answers.parallel, current increases until too many bulbs have been added, then circuit breaker pops and current drops to zero.series, current decreases and all bulbs dim.
In a series circuit, if one component burns out, the circuit will not work because the current flow is interrupted by the burnt-out component. This is because components in a series circuit share the same current.
When your circuit is in SERIES, each individual bulb will receive one fraction of the voltage of the battery, allowing the full chain of bulbs to draw less current, but to be dimmer in the same respect. When your circuit is in PARALLEL, each bulb will receive the same voltage, however more current will be drawn, so it depends on your situation on which you should use.
The recommended type of 60 watt bulbs for use with a candelabra are candelabra bulbs.
An electric current flowing in only one direction is called direct current (DC). This type of current has a constant flow of electrons in one direction from the negative to the positive terminal of a power source, such as a battery.
