Diagrams and expert advice take the mystery out of wiring 3-way switches—the type that controls lights from two places. Wire your 3-way switches like a pro!
Sometimes, you can run the display interface command (or monitor the interface bandwidth on the NMS) to check whether the interface bandwidth usage is only 30% to 40%. If the value of the Output peak rate field is not large, you may ignore packet loss triggered due to the traffic ...
Ensuring the performance of automotive electronic control units (ECUs) requires rigorous testing against various operational conditions to meet compliance. Learn how autoranging power supplies can help ensure the automotive ECU power performance is relia
Outlet cover plate Adding an additional light fixture and powering it from an existing gang box is not complicated if you expand the existing gang box and power both lights with separate switches. Some gang boxes are in locations that do not allow the box to be expanded to add a separate l...
It would beagainst codeto wire receptacles in series, and there's no good reason to do it anyway. The total voltage in a series circuit equals the sum of the voltage drops, which means if you have something plugged into each of the receptacles, the voltage of the series outlet at the ...
Turn on the switch. Want to listen to your iPod? Push the wheel at the front and that activates a switch that turns on the power. But sometimes we want electrical and electronic circuits to be activated in other ways. Suppose you want to wire up a bank safe so it triggers an alarm ...
either because room temperature at the thermostat has fallen below the thermostat setting OR because the occupants turn up the thermostat to a higher temperature setting. The thermostat, acting like a simple on-off switch, tells the furnace, through low-voltage electrical wires connected to a contr...
Rogowski coils are similar in that they wrap around the load wire but they are flexible, have a much larger opening than standard CTs, and the principle of measurement is different. Rogowski coils induce a voltage that is proportional to the rate of change of Current and thus require in ...
How to set up a VLAN Connect to switches using Secure Shell (SSH) orHTTPS. Network administrators can use a web-based GUI or commands at the command prompt, depending on the switch interface. Authenticate each switch, and create the VLANs according to the network map. The commands resemble...
end that you can use to connect external devices to your Arduino. Each pin plug can connect to one pin on your Arduino. For example, one wire could be connected to pin 13 (which will be used in this tutorial) and one other wire could be connected to the ground pin to power atiny...
