When three light bulbs are in parallel the voltage V on each is the same. Each bulb draws a certain amount of current, i1, i2, & i3. If all three are working they draw a total current I = i1 + 12 + 13 from your power source. And the energy they use is ,I x V. When one bulb goes out then the only thing affected is i3 = 0. The voltage is the same but the total current from your power source is less and therefore the total energy used is less. So nothing happens to the other two bulbs (that's one reason why all household outlets are in parallel) and you just use less energy.

How many type of electric circuit?

There are basically two types of circuits: parallel and series. In a series circuit, current flows in one continuous straight path. In a parallel circuit, the current has more than one path to follow.AnswerThere are four categories of circuit, not two. These are 'series', 'parallel', 'series-parallel', and 'complex'. A 'complex circuit' describes any circuit not falling into the first three categories.


Three electric cells each have a voltage of 1.3Vwhat is the total voltage of the three cells if the cells are connected in parallel?

voltage is still 1.3V in parallel circuit, voltage stays the same but current adds up in series circuit, voltage adds up but current stays the same


When three bulbs connected to a battery in parallel circuit what will happen to the brightness of the bulbs?

The brightness of three bulb would be mare than one


When would a parallel circuit work better than a series circuit?

Efficiency isn't the question. They just do different things. For example, if you look at a typical lighting circuit in a house, all the bulbs on a circuit are in parallel. They each have the same voltage across the bulbs. If you rewired this so that the bulbs were in series then the voltage would be divided across each bulb and if one bulb burned out the others in series would get no current and would not light. If you had two 60Watt bulbs in parallel in your house, each would draw 1/2 Amp. Add another bulb and it would draw 1/2 amp as well, for a total of three 60W bulbs drawing 1.5 amps from the power source. If the same three bulbs were in series there would be 40 Volts across each one with a current of 1/6 amps per bulb. Hence each bulb would be about 1/3 as bright as in the parallel circuit.


What would be the voltage suplied to each circuit if three circuits are connected in parallel with a power supply of 30 volts?

30 volts.

What are the three types of circuit's?

the three types of circuits are series, parallel, and series-parallel.AnswerThere are, in fact, four types or categories of circuit, not three! These are series, parallel, series-parallel, and complex.The term 'complex' is somewhat misleading, because a 'complex circuit' is not necessarily complicated (although they often are!) but merely the collective name for any circuit that isn't series, parallel, or series-parallel. A simple example of a complex circuit is a bridge circuit, such as Wheatstone's Bridge.


How many pathways are there in a parallel circuit witn theree bulbs?

In a parallel circuit with three bulbs, there are three separate pathways for current to flow, one for each bulb. This means that each bulb has its own independent connection to the power source, and if one bulb were to fail, the others would still light up.


If one light bulb is removed from a parallel circuit with three bulbs the brightness of the other bulbs will decrease True or false?

False. In a parallel circuit, each light bulb operates independently, so removing one bulb does not affect the brightness of the others. The remaining bulbs will continue to receive the same voltage as before, maintaining their brightness.

Do nothing. But in a parallel circuit, all the bulbs will get dimmer.


What is the parallel disadvantage circuit?

There are three disadvantages of parallel circuits. These include the fact that they have complex resistance, voltage that is limited, and a current that varies.


What happens when one light bulb out of three goes out in a parallel circuit?

What is the three laws of parallel circuit?

The potential difference remains the same over the components in parallel and the current splits up proportianally to the components conductances. The components conductances add up to give the combined conductance of the parallel circuit. Conductance is 1 / resistance
