How do you make a short circuit?
When the electrical appliances are not connected well or the cables of the electric appliances are worn out,a short circuit may occured. A short circuit affects the normal operation of electrical appliances connected to the circuit.It has very low resistance that almost all electric current would flow through it.Owing to the heating effect,an excess electric current would produce heat and thus may damage the electric appliances,or even cause a fire,if without a fuse or a circuit breaker.
Can a graph have an Euler circuit but not a Hamiltonian circuit?
Yes. An example: _____A---------B________ A connected directly to B and D by one path. _____|_______/|\________ B connected directly to A and E by one path, and to C by two paths. _____|______/_|_\_______ _____|_____/___\_|______ _____|__E/_____\|______ E connected directly to B and D by one path. _____|____\_____C______ C connected directly to B and D by two paths. _____|_____\____|\_____ _____|______\___|__\___ _____|_______\__|__/___ _____|________\_|_/____ _____|_________\|/_____ _____-------------D_____ D connected directly to A and E by one path, and to C by two paths. There is an Euler circuit: ABCDEBCDA But a Hamiltonian circuit is impossible: as part of a circuit A can only be reached by the path BAD, but once BAD has been traversed it is impossible to get to both C and E without returning to B or D first. However there is a Hamiltonian Path: ABCDE.
What is advantage of ac generation rather than dc generation?
!! In india and most of the other countries user ac current. Hence, all the appliances are ac dependable. So generating ac directly would allow up to directly feed the appliances without any converter circuit.
What is the total power when several electrical appliances are connected in series?
In a normal household configuration, the appliances are connected in parallel. This allows each of them to draw the amount of current they were designed to operate on. Unless you wired your own extension cord, you cannot connect them in series. Theoretically speaking (I hope you keep this theoretical), the loads in series increases the resistance of the circuit, which decreases the current through the circuit. None of the appliances would work properly. The more you connected, the less functional they become. There may be some other safety issues with their design compromised, but the appliances would not function properly and it is not possible to answer the question without some information about the appliances and power specs for each. Then it can be translated into a mathematical question.
What happens to the overall resistance of a circuit when too many appliances are connected across a 120 V outlet?
This is a very technical electrical question that may be difficult to understand without further study. But adding appliances to an outlet is the same as adding resistance in parallel. Adding resistance in parallel, the resistance of the circuit goes down. That is why you get more current flow. By contrast, adding resistance in series increases the resistance of the circuit and therefore reduces current, all else being equal.
What is the name of a series circuit?
An electric circuit connected so that current passes through each circuit element in turn without branching.
Can the car run without the negative terminal connected?
The negative teminal needs to be connected to complete the electrical circuit. Without that none of the electronics in the vehicle will work, including the starter.
When do you get a short cicuit?
A short circuit is said to have occurred when the supply and return wire are directly connected without first passing the electrical current through a device which uses the current. For example, if you have two wires that are supposed to operate a light bulb, but instead you connect them together, that would be a short circuit.
Can you use a laptop without connecting to a computer?
A laptop IS a computer. They can certainly be used for most applications without being connected to anything. Many have wireless capability and can connect to the internet without being directly connected to anything else, but they are connected, it's just wireless.
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.
How do you decide which appliances can be used in a circuit without overloading it?
each appliance should have a rating label showing the amps or watts used, Add up these figures to see if they exceed the capacity of the circuit. Amps =watts/voltage
Can a Laptop with wireless be used with cable modem without a router and not plug into the cable modem directly?
If you want to have internet on that laptop you need to be connected to internet provider which usually happens directly (connected to the modem) or indirectly (connected to the modem through wired or wireless router).
