3 phase hots does it matter where the wild leg goes?
Your question is not very clear, but usually the higher voltage 'wild leg' goes on the "B" phase terminals in breaker boxes. However, I have seen it on the "C" phase as well.
What is 7815 voltage regulator?
A LM7815 voltage regulator is a component designed to maintain a constant voltage level, the LM78XX series of voltage regulators are designed for positive inputs and has the ability to drive the current within the circuit up to 1A. The component has three legs: Input leg which can hold up to 36VDC, a leg that leads straight to ground and an output leg with the regulated voltage. For maximum voltage regulation, adding a capacitor in parallel between the ground leg and the output leg will improve efficiency.
What is the purpose of routers?
Routers are responsible for delivering and receiving network communication. They regulate what goes in from either "leg" of the router and what goes out of either "leg". They can also be configured to send specific data through specific routes, hence the name. The purpose of routers is to take the signal that is being sent via the cable wire and convert it into a wireless signal that multiple devices can connect to.
Leg or filet weld?
Leg of the weld. Fillet is the part you cut off e.g. a corner...
What is difference between two leg stirrup and four leg stirrup in bar bending schedule?
When we use a single stirrup to tide a beam or column at a time, we say it is two leg stirrup and thus if we use Double stirrup to tide a beam or column at a time, we say it is four leg stirrups. A single stirrup have two leg. _(Er. Aabid Iqbal)
How can you identify the positive leg and negative leg on an Electrolytic capacitor?
The positive leg is usually indicated with a red dot. Sometimes there is an white arrow that looks like a minus sign - that is the negative terminal. If it is a can type, the can is the minus terminal and the tab(s) is(are) the plus terminal(s).
How can you identify a negative leg on a LED?
the negative leg is shorter than the positive leg.
In an LED how can you work out which leg is negative?
because the negative leg is shorter.
Is the leg positive or negative?
A leg is a limb, it is neither positive or negative.
What are the 2 ways to find out which is the positive leg and which is negative - led?
On an LED, one leg will be shorter than the other. The shorter leg is the negative polarity.
Does it make a difference how you wire a capACITOR?
If the capacitor is and electrolytic then YES, you must keep the +ve to the side with no marking or a + and -ve to the side with a stripe or a - on it. If the capacitor has one leg shorter than the other the shorter leg is also the -ve side. Connecting an electrolytic the wrong way round can cause it to boil or even explode. If it is not electrolytic then it can go either way round, these are usually smaller.
How could you identify the negative leg of a LED if both legs were cut the same length?
Look at the size of the 'flags' inside the LED lens itself. The bigger one is the positive one. Don't ask me about a bi/tri colour LED, maybe with a capacitor.
What is a Hurkey jump?
A "hurkey" is a jump where one extended leg goes in front of you and one extended leg goes behind you.
What goes on your leg if you break?
cast
Why are led legs different in size?
Current will only flow one way through an LED, so it has a positive leg and a negative leg. One of them is longer to signify which is which (longer is negative). The negative side also has a chamfered edge on the LED itself.
What is the negative leg of an LED called?
The side of any diode that must be negative in order for the diode to conduct is the "cathode".
What is the short and long legs of LED called?
Cathode (negative) is the shortest leg and there is a flat edge on the base of the LED, and it must be connected to the negative wire or "-" connection. Anode (positive) is the longest leg, and must be connected to the positive wire or "+" connection, as electricity will only pass through a LED from positive to negative.
