If the light bulbs are connected in parallel, the currents through the light bulbs combine to form the current in the battery, while the voltage drop is 12 volts across each bulb and they all glow. In a series circuit, every device must function for the circuit to be complete. If one bulb burns out in a series circuit, the entire circuit is broken.
In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.
Low-frequency induction can be a dangerous form of inductive coupling when it happens inadvertently. For example, if a long-distance metal pipeline is installed along a right of way in parallel with a high-voltage power line, the power line can induce current on the pipe. Since the pipe is a conductor, insulated by its protective coating from ...
All are based on the same principle, which is to compare the output of two potential dividers sharing a common source. In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e. to convert it from an unknown or alternating polarity to a direct current of ...
For example, chaining multiple components that each have a UART port to each other. The components must also behave cooperatively. e.g., only one seizes the communications bus at a time. SCSI is an example of a digital system that is electrically a bus, in the case of external devices, is physically wired as a daisy chain. Since the network is ...
Two sets of cables (such as in the corner of a room where two walls meet) can be connected together with short wires that have clips (such as alligator clips or screw clamps) at either end. Another variation is called flex track or monorail track lighting in which the fixtures are hung from a single line monorail track attached to the ceiling ...
For example, a green LED is sensitive to blue light and some green light, but not to yellow or red light. This implementation of LEDs may be added to designs with only minor modifications in circuitry. [10] An LED can be multiplexed in such a circuit, such that it can be used for both light emission and sensing at different times. [10] [12]
This also applied for pulling wire into the factory through conduit or in trays where each wire would have corresponding numbers. Wire labels were typically pieces of white tape with numbers or letters printed onto them and collected in small, pocket sized booklets. A number strip would be peeled out and wrapped around the wire near the end.
