Should a resistor go on the positive or negative side of an LED?

It does not matter. Kirchoff's Current Law states that the signed sum of the currents entering a node is zero. A consequence of that law is that the current in every part of a series circuit is the same.
The only thing that resistor location affects is the potential voltage of the LED terminals with respect to the rest of the circuit. Certainly, if you are driving the LED with high voltage, such as 120VAC, you should consider the resistor location so as to reduce electrocution hazard but, the LED's performance is not affected by resistor location in the circuit.

When an ammeter is connected in a circuit which terminal of the battery must be connected to the positive terminal of the ammeter?
The positive terminal of the battery would be connected to the positive terminal of the ammeter. The load would then be connected between the two negative terminals, positive side of the load being connected to the negative side of the ammeter.
How do you install a resistor in an DC circuit?
It depends on the purpose for installing the resistor. If the intent is to decrease current flow, the resistor must be connected in series with the load. If the purpose is to increase current flow, the resistor must be connected in parallel with the load. To connect a resistor in series, connect the resistor to one side of the power source, in line with the load. This will decrease circuit current flow. To connect a resistor in parallel, connect the resistor between the positive and negative sides of the power source, which will effectively connect the resistor across the load . This will increase current flow through the circuit. However, before connecting a component in parallel, make sure the increase in current flow will not exceed the current rating of the circuit or fuses/breakers will blow.
The triangle in a diode symbol points in the direction of?
it points in the direction of flowing current due to majority carriers... that is from positive side to negative side
In an electric circuit why do the electrons go from the positive side of the battery to the negative side?
The short answer is that they don't. But that doesn't help you much. Electrons flow from the negative terminal to the positive terminal. Why? Negative and positive (opposite) charges attract each other, and like charges repel each other. So you can think of the positive charged end pulling electrons towards it, as well as the negative charged end pushing electrons away from it. Water makes a good analogy, the battery is a pump, so there is high pressure on the outlet of the pump ( the negative terminal ) through the pipes and whatnot, ( the wire and whatnot) to the inlet of the pump ( the positive charged end ).
How is reverse current in a diode produced?
The main reason for produce reverse current in a diode is "MINORITY CARRIERS". For reverse bias diode i.e negative terminal connected to p side and positive to n side the electrons in p side(minority charge carriers) attracted towards the positive polarity i.e towards positive terminal. Hence the current (reverse saturation) flows.Holes also contributed the current by attracting towards negative side.
Does the AC outlets have a positive and negative terminals?
The side of the plug with the ground wire is or should be the negative and the side with just the center screws is the positive.
What if battery is not marked positive or negative?
usually it should, but if it doesn't show then the flat side is negative and the tip is positive, On an automotive battery the larger post is positive +.
How do you use an ammeter?
The Positive side of the Ammeter should be connected to the positive side of the battery and the Negative side should be connected to the Globe/Conductor/Insulator to provide a valid reading.
How can you tell what side is negative and what side is positive?
Large side is negative
Does energy flow through the negative or positive of a battery?
Negative side
Why do batteries have a positive and negative side?
they do because like magnets we have negative and positive ,negative and negative repel and vise verse but positive and negative attract
Does it have a positive or negative impact?
The best way to determine if a course of action has a mostly positive or negative impact is to create a list. One side should detail the decision's negative effects, while the opposite lists its positive. The side that has the most entries is generally considered the appropriate answer.
Should both negative and positive sides of a coil in a 71 dodge dart be hot?
No, just the positive side is hot.
How do you connect and measure voltage using a voltmeter?
with a voltomiter
On a 96 Nissan Sentra witch side is positive and negative on the starter?
should only be one post.. and that would be the positive.. should be self grounding
Is the anode side of a batteries the positive side or the negative side?
" Anode " is generally refer to POSITIVE. Cathode generally refer to NEGATIVE. But these terms are use for different applications ( For example: you wouldn't refer to the POSITIVE side of a battery as ANODE or NEGATIVE side as CATHODE, it commonly refer as positive or negative when you are dealing with battery application etc. )
In a schematic drawing of battery is the long side the positive side or the negative?
The positive
