Will a circuit work if it has a breAk in it?
No because for electricity to go around in the circuit it has to be closed.ok here's how I learned it the wires to the electricity is is like the rollercoaster track to the car so if the circuit isn't closed or the rollercoaster track has a giant gap either the electricity won't go through or the people will fall
Why do the resistance is zero in case of short circuit?
The current is 0. Current is the unit of flow of electrons in a circuit, and in an open circuit, electrons cannot flow. Therefore there is 0 current. Another way to look at it is that I = V / R, where I = Amps (current), V = voltage, and R = resistance (impedance). In an open circuit, the impedance is infinite, and by using our math skills, we know that X (or V in our case) divided by infinity, is 0. I = V / Infinity = 0
Why parallel circuit connection is used in common wiring practice?
A parallel circuit is used in common wiring practice because it allows one item to go out and the rest will remain on. Say that you had an office building. If every light bulb in the place was connected in series(every light bulb connected to the next on one current path), if one were to burn out, the circuit would break and all the other bulbs would go out. By using a parallel circuit, one bulb can go out and the rest can stay lit. Another reason that this occurs is because of the resistance involved in a series circuit. By connecting everything in one path, resistance to current will grow rapidly, so and current supplied to the circuit would be wasted by the resistance. Connecting in parallel gives multiple pathways for current to travel between devices and power sources, so the resistance is much lower, and more of the energy goes to powering the device rather than overcoming resistance.
If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
How are circuit breakers connected with the other elements in a circuit?
Both of these devices are safety devices used to open a faulted circuit and stop the current flow.
When a circuit is open do electrons go backwards or do they just stop?
When a circuit is open, electrons do not flow at all. They do not go backwards or stop within the circuit because there is no complete path for them to move through.
What are the similarities between the circulatory system and an electrical circuit?
in order for a circuit to work the whole circuit has to be connected, just like the circulatory system. The heart pumps the blood around the body so that the oxygen in the blood can go around the body to the required organs or muscles. In a circuit the battery pumps the electrons around the circuit so that the bulb is able to work.
Are all the electrons flowing in a circuit provided by the battery?
because they only form a single path then the electron flow in one way if they have parallel the electron go between lines and go off. i order to have eletri flow you need to have single line.
How many path ways are available for electrons to travel in a series of circuit?
In a series circuit, the electrons have only one path to travel from the negative terminal of the battery, through the components, and back to the positive terminal of the battery. This is in contrast to a parallel circuit, where electrons have multiple paths to choose from.
What particles around the atom have negative charge?
Electrons, which orbit the nucleus of an atom, have a negative charge.
Do the electrons go left or right?
Electrons were generally thought of as individual electrons that rotate around a nucleus; however, they look more like a cloud around a nucleus and are in all places at the same time.
Where does electrical current go after it is used in the home?
It is transformed into energy thus causing heat, but the electricity won't go anywhere, remaining inside the wires on the form of electrons when not flowing. When any electric device is turned on, the electricity begins to circulate again within the circuit.
Does a current always follow a closed circuit?
Yes, a current requires a closed circuit to flow. Without a closed path for the electrons to travel through, the current cannot be established. The circuit provides the complete loop necessary for the flow of electrons.
The electric current in a medical conductor is carried by positive electrons or electrons?
The answer is electrons. I assume you mean positrons (anti-electrons) by positive electrons, and positrons and electrons go boom when they meet, so we don't see many positrons around.
In an electric current electricity flow how?
Electricity can flow in an electric circuit by a battery. The battery creates electrons, which flow through the wire, and then go into a light bulb. (That is how a light bulb in a circuit lights up.) A series circuit is a circuit with one wire that electrons can flow through. Also, there can be more than one light bulb connecting to the same wire. A parallel circuit is a circuit with light bulbs that have their own wire.ClarificationThe above answer, unfortunately, perpetuates the myth that current leaves a battery, and finds its way around a circuit. This is not the case at all. It is the load that 'draws' the current from the battery and it is the load that determines the size of that current.
What happens to the flow of electricity in an incomplete circuit?
It stops flowing. An analogy to this is the kitchen faucet ... water is always "at the ready" behind the valve, ready to flow when it is enabled. Same is true in an electrical circuit - once the circuit is broken (valve closed in above analogy) the flow of electrons ceases. If there is a light bulb which is not on it is a open circuit. If the light bulb is still on it is parallel circuit which has lot of wires causes some of the lights to go on and some to go of.
What direction does a resistor go around in an electrical circuit?
It doesn't matter which way round you place it.
