Arrowheads were more likely to be seen as good luck than bad luck, including in Europe and Britain, but they are unlucky according to some traditions. Since they were weapons of war, some people associated them with evil.

What does finding an arrowhead mean?

The arrowhead, specifically, is rooted in protection and security. Native Americans have long believed that wearing an arrowhead around your neck is a symbol of protection and strength. It has also acted as an icon of courage, protecting whoever wore it from illnesses and negative energy.

What do arrowheads mean spiritually?

It symbolizes bravery, achievements, heroism, spirit guides, and significant event in their life. These days, the arrowhead is also used as a pendant. Arrowhead is more than just a weapon. The pointed part of the arrowhead can easily penetrate the skin.

Are real arrowheads worth anything?

Since they are so common, you wont be able to sell a typical arrowhead for much. However, some arrowheads are worth much more than others. An arrowhead can be worth $20,000 in the best cases, even though it might only be worth $5, and an average arrowhead is only worth about $20.

What is the significance of arrowhead in the transistor symbol?

The arrow indicates the direction of flow of holes i.e. the direction of conventional current, opposite to the flow of electrons in a transistor.

What is the need of biasing?

Biasing is the process of providing DC voltage which helps in the functioning of the circuit. A transistor is based in order to make the emitter base junction forward biased and collector base junction reverse biased, so that it maintains in active region, to work as an amplifier.

Which of the transistor current is always highest?

emitter current IE The emitter current IE is always the largest one. The base current IB is always the smallest. The collector current IC and emitter current IE are relatively close in magnitude.

How do you identify an arrowhead?

In case its stemless, see if its fluted or not. If its scored, determine if its indented in the side or from the corner. The area and the configuration of the pointed arrowhead are sufficient to limit your options to just 12 potential types.

What is the use of re resistance?

The aim of an AC signal amplifier circuit is to stabilise the DC biased input voltage to the amplifier and thus only amplify the required AC signal. This stabilisation is achieved by the use of an Emitter Resistance which provides the required amount of automatic biasing needed for a common emitter amplifier.
