In series
That is a series circuit. An example is old christmas tree bulbs where if one burned out they all went dark.
Do nothing. But in a parallel circuit, all the bulbs will get dimmer.
The equipment is all connected in series with each other to make a complete electrical circuit.
help :(
As they are connected in parallel (each has its own branch) the remaining bulbs keep shining exactly as they did before.
It depends on the circuit. If it is a constant-current circuit, any light bulbs connected in parallel with it will become brighter. If it is a constant-voltage circuit like a typical household circuit, nothing will happen. Any connected in series with it will go out.
Because the ammeter connected in parallel will act as a short circuit.
The circuit voltage or the resistance of the individual bulb is needed to answer this question. Divide the total power (400 W) by the supply voltage.
If a fourth bulb were added in a similar way to the three existing bulbs, the resistance in the circuit would go up if the bulbs were series connected, and it would go down if the bulbs were parallel connected.
In a series circuit with two light bulbs, if one bulb goes out, the entire circuit is interrupted. This means that electricity cannot flow through the circuit, causing both bulbs to go dark. Since the bulbs are connected in series, the failure of one component affects the entire circuit's functionality. Therefore, both light bulbs would stop working until the faulty bulb is replaced or repaired.
The bulbs are in connected series. There was a short circuit and the circuit breaker tripped.
They can be connected to either supply. A bulb in series that fails, will cause all the other bulbs to go out. A bulb in parallel that fails, will have no adverse effect on the other bulbs in that circuit
