When several outlets are on the same circuit the current comes first from the breaker panel to one outlet where it is connected to a duplex receptacle and/or switch or light, then to the NEXT outlet, light or switch. If a connection was not made properly at any point along the way it can corrode or somehow loose connection back to the breaker panel. If that happens, every outlet DOWNSTREAM will not be working properly. If you cannot track down the problem yourself, you will need to hire an electrician.
Routers operate at layer 3. LAN switches operate at layer 2. Ethernet hubs operate at layer 1.
An electrician does not operate breakers he installs them.
Hubs are a physical layer (layer 1) device; most switches operate at the Data Link layer (Layer 2) of the OSI model.
easy to operate
Most switches operate at layer 2 or the Data Link layer.
Transistors are designed to operate as being either opened or closed, or off or on.
Does this car have a safety lockout of the passenger switches? It's probably activated. If it was just one passenger window I would suspect a broken wire, most likely in the rubber bellows between the door and frame.
A circuit breaker will run "warm" when under heavy load. Like with AC It should never get so hot you can't touch it. <<>> Circuit breakers are designed to operate within their correct tripping value at 50 degrees C above ambient air temperature. The size of the breakers frame has a bearing on how hot the breaker can operate. The larger the breaker the more surface area to dissipate the generated heat. The heat that is generated inside the breaker is from the contacts and the bi-metal trip. These are typically the hottest parts within the breaker. To answer the question, a circuit breaker will get hot on very hot days but as long as the breaker stays within the its parameters it will operate as it should.
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
Yes. Most switches (which operate at layer 2) will NOT route packets between different subnets. However special layer 3 switches DO have this capability.
Appliances like electric mixers use a high amperage to operate. It will be in the upper limits of the circuits breaker. The most likely scenario is that there is some other device also connected to the same circuit. The total combination is what is tripping the breaker. Another problem could be the mixer itself. These types of appliances usually use brushes to operate the motor. Check or take the mixer to an appliance repairman to check to see if the brushes have worn down and are shorting causing the breaker to trip.
Circuit breakers operate on current not voltage.
There is a relay switch in the circuit which switches the light on & off when you activate the turn signal.
Yes, the reason being with no electricity nothing will operate. Leave the main breaker off for a month and your bill will be $0.00
Water pressure switches work as monitors in a well system. These operate electrical controls and circuits that turn on and off depending on changes in water pressure.
There are no switches that operate on layer 7 (Application layer) on the OSI Model. Switches are a layer-2 device because they manage and switch frames.
If you are talking about intermediate switches, the switches that are in the middle of the three way (UK two way) circuit, then you can add as many as your project needs. These type of switches must be in the middle, as if installed on the end, the different position switching will not operate.
I had the same problem with our 1998 Pontiac GP. Both windows suddenly failed to operate. Checked the circuit breaker, that was fine. Could not find any other type of fuse related to the windows. The answer? The electrical pigtail that should have been plugged into the two window operating switches on the drivers side door had come loose. Once reconnected, all was well. (To access the wiring, just GENTLY pry up the switch panel from the bottom - below the two window switches.)
Not really - they operate at the Data Link layer using the MAC address and therefore don't really segment a network. There are some managed switches that can do this or by using VLAN configurations, but ordinary switches will not really segment a LAN.
the crankshaft pos sensor controls the relay switches which operate the fuel pump and the electricity supply to the coil causing no spark to reach the distributor YES
