If you have 2 5-watt bulbs connected in series and then in parallel which circuit arrangement will give you brighter bulbs?

It depends on the voltage rating of each lamp, and the value of the supply voltage. It's important to understand that a lamp will only operate at its rated power (therefore at its full brightness) when subject to its rated voltage.
So, let's assume each lamp is rated at, say, 24 V.
If connected in parallel across a 24-V supply, then they will both operate of full brightness.
If connected in series across the same 24-V supply, then each lamp will be subject to half its rated voltage, and will be very dim.
On the other hand, if connected in series across a 48-V supply, then they will each be subject to 24 V, and will both operate at full brightness.

∙ 15y agoThe 5 watt bulb will glow brightly. The reason has to do with resistance. The higher watt bulb will have the lowest resistance. When you put the two in series, low resistance causes the lowest voltage drop. Higher resistance causes higher voltage drop, therefore the lowest wattage (highest resistance) bulb will have more voltage across it than the other bulb, and will glow brighter.

Which circuit the ammeter connected in parallel?
An ammeter is always connected in series and a vlotmeter in parallel
How is a series circuit different to a parell circuit?
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
A circuit contains a 10 pF capacitor and a 50 pF capacitor connected in parallel.What is the total capacitance of this circuit?
When capacitors are connected in parallel, the total capacitance in the circuit in which they are connected is the sum of both capacitances. Capacitors in parallel add like resistors in series, while capacitors in series add like resistors in parallel.
What is a resistance network?
A resistance 'network' consists of a number of resistors connected together in series, or in parallel, or in series-parallel, or as a complex circuit. A 'complex' circuit is one that is not series, parallel, or series-parallel.
How do you check dc voltage... series or parallel?
If you are asking how a voltmeter should be connected in a circuit, then the answer is that it should be connected in parallel with the device across which you want to determine the voltage. This applies whether the circuit is d.c. or a.c.
Light bulb in parallel circuit brightness?
Two bulbs connected in parallel are brighter than two connected in series. The resistance of the circuit is lower, electrons can flow more easily.
What type of circuit will produce brighter lights is it series circular direct or parallel?
Parallel connections will draw more current than equivalent lights connected in series, so the parallel configuration will be brighter.
If you have two 5 watt bulbs connected in series and then in parallel which circuit arrangement will give you brighter bulbs explain your answer?
Brighter in parallel. In series the voltage is divided between the two bulbs, thus the current will only be half so that the power of each bulb will only be one quarter (of 5 watts) in the series set-up.
What is the equivalent resistance of the parallel circuit you have connected?
In principle, it is infinite. I have not connected a parallel circuit in ages.
If both series and parallel circuits have 1 cell and 3 lamps, which type of circuit would be brighter?
Parallel circuit.
How are the loads in parallel circuit connected?
Parallel to each other.
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
What happens to supply voltage if additional resistance is connected in parallel circuit?
No change in supply voltage as additional resistance is connected in parallel circuit.
What is a circuit in which loads are connected side by side?
A circuit in which loads are connected side by side is known as a parallel circuit.
What is a circuit connected in a single path?
parallel
How should a ammeter and voltmeter be connected in circuit?
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
Is the voltmeter always connected in series to the circuit?
in parallel
