The longer wire is the positive end, but if the wires are the same length, check inside the LED. There are two easily seen parts connected by a wire, the smaller is the positive.

How can you tell the difference between positive and negative wires?

One way to tell the difference between positive and negative wires is by their color coding. Positive wires are typically red, orange, or another bright color, while negative wires are usually black or another dark color. You can also use a multimeter to test for voltage: the positive wire should show a higher voltage than the negative wire when tested.


How can you distinguish between positive and negative terminals?

Positive terminals typically have a red color or a "+" sign indicated, while negative terminals are usually black or have a "-" sign marked. Additionally, positive terminals are connected to the cathode, while negative terminals are connected to the anode in a battery or electrical device.


How can you tell if acceleration is positive or negative?

Acceleration is positive when an object is speeding up in the positive direction (e.g., increasing velocity), and negative when the object is slowing down in the positive direction or moving in the negative direction (e.g., decreasing velocity). The sign of acceleration depends on the direction of the change in velocity relative to the direction of motion.


Can you tell if an object has a positive or negative charge with a electroscope?

Yes, an electroscope can determine if an object has a charge, but it cannot distinguish between a positive or negative charge. If the object causes the electroscope's leaves to diverge, it indicates the presence of a charge on the object. Further experiments or additional methods are required to determine the polarity of the charge.


Positive and negative effects on clocks?

Positive effects of clocks include helping us to manage our time effectively, stay organized, and improve productivity by keeping track of schedules and deadlines. However, a negative effect of clocks can be that they can create stress or pressure to always be mindful of time, leading to feelings of time constraint and urgency.
