Why does an electric bulb not become dim when another bulb of the same power in a parallel circuit is switched on?
The reason that neither lamp is affected by the operation of the other is that each one can "see" the applied voltage whether the other is on or not. Each is "directly connected" to the source, a lamp's operation is unaffected by the other lamp. Trace the flow of current from the source through a lamp and back to the source. The other lamp is not in that circuit, and it will not have an effect on the lamp being inspected. This is the nature of a parallel circuit. Each branch in a purely parallel circuit is directly connected to the source and operates as it does without any regard whatsoever as to what may or may not be connected in parallel with it.
What happens in a parallel circuit when a component breaks?
This depends if the component was wired in series or in parallel to the rest of the circuit. When a component breaks, it stops functioning and cannot conduct electricity. If it is wired in series to the rest of the circuit, the entire circuit will cease functioning. If it is wired in parallel to the rest of the circuit, the circuit will continue functioning, but with more electricity going to the other line.
How does light bulbs in a circuit affect the current size?
They don't unless you speaking about a parallel circuit in which total currect would be the sum of all the currents in each light bulb (The more light bulbs, the more current draw) If you're talking about a series circuit, nothing at all happens to the current, as in a seires circuit current is constant throughout the entire circuit (voltage changes). In a case such as this the more light bulbs in the circuit, the less the voltage becomes across those bulbs (furthest from the source), thus they will become dimmer due to lower power (P=IE).
How does matter become charged?
Matter becomes charged by electric charges, static electricity and an electric field.
What does series mean in series circuit?
In a series circuit, the loads are connect much like the cars of a train, with the output of one device - a resistor, for example - connected to the input of another. With the source and all loads connected, the components will be connected together much like the links of a bracelet, with no alternate paths for current flow. If one load device becomes open, then all devices will be de-energized. This is opposed to a purely parallel circuit, where all of the load device inputs are connected to one side of the source, and all of the load device outputs are connected to the other side of the source. This provides a separate path of current flow for each load device. Should one or more load devices become open, the remaining devices will continue to function, due to the alternate current paths. In series-parallel circuits, there is a combination of both types within the same circuit. Any combination of series and parallel paths can exist within the circuit.
What happens if there is a break in parallel circuit?
If the break is in either the feeder or return line, the circuit will become open and the circuit will cease to function.

When does electric become hazardous to humans?
when it completes a circuit in the body
When you short out a resistor in a parallel circuit why does the current lower?
The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values, and then taking the reciprocal of the total. By removing a resistor the total current will lower. If you short out the parallel circuit as suggested it will take out the fuse that should be protecting the circuit.AnswerShorting-out a resistor in a parallel circuit, will act to short out the entire circuit, therefore, significantly increasing, not lowering, the current! And, as the previous answer indicates, this short-circuit current will operate any protective devices, such as a fuse.In a parallel circuit current does not lower but it will be increase if shorting-out one resistor in the two resistor parallel circuit, the circuit will become very low resistive and the larger current will flow through the short path.
Why a spark is produced in the switch of a fan when it is switched off?
when inductive load is switched off then current decreases as a result emf induced in the inductor or as whole of the circuit. There is air between switch and circuit wire. Emf tends to jump from higher pd to lower pd so air become ionised and spark is prouced

Some names of circuit cars are Mustang, Ford, General Electric, and others. Circuit cars are a pretty new concept around the world and is emerging to become very popular.

How come a series circuit is not used for car headlights?
Because you need to use a parallel circuit. With a series circuit, the car headlights will become dim. This is because, the electricity in a series circuit goes only one way and this means that when there are 2 bulbs, the charges of electricity have to use half of their energy for each bulb.
What would happen if one of a set of light bulbs burn out in a parallel circuit?
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.
Why ammeter works as short circuited in circuit?
The ammeter is basically a Galvanometer with a small resistance to parallel with it. As we know that, if we connect two resistances in parallel, then the equivalent resistance is equal to the the value which is less than the value of lowest resistance connected in parallel. suppose if we connect 1 ohm & 0.1 ohm in parallel, then the equivalent of it will be 0.0909 ohm (less than 0.1 ohm). means in parallel circuit the equivalent resistance become smaller. as like this a small parallel resistance across galvanometer decreases the value of the value of resistance of it. since it gets very small value, so it connected in series to measure the value of current in the circuit. due to very low resistance, it drops very low voltage on it ( upto can be negligible) so we assume that it works like a short circuit.
Why are the wingspans of birds a consideration in determining the spacing between parallel wires in a power line?
If the wingspan of birds is sufficient to span the wires that differ in electric potential, then the bird acts as a path for current to flow from the high voltage wire to the low voltage wire. Since the electric potential differences are huge in power lines, it is very likely that the bird will be cooked when it completes the circuit and the ground below will become littered with carcasses.
