Electric currents serve multiple function in our everyday lives. Watch the video above about smart band-aids and answer the following questions.

1. Explain the science behind smart band-aids. (35 points)
2. What are some practical applications of the smart band-aids. (35 points)
3. Do you think smart-band-aids will become more popular in the future?
Why or why not? (30 points)

1. smart band-aids can detect the presence of bacteria on the cut by changing color and release antibiotic

2. They are applied when a person is cut or to fasten the healing processes of a wound

3.Smart band aid are the future of diagnosis and treatment of wound infection

Explanation:

Smart band aids are designed in a manner that the adhesive bandage protects the wound from dirt , bacteria and physical damage.This ensures that the affected area is not disturbed during its healing processes. The bandage enhance the time of healing to be faster by bringing the two cut parts of the skin together. Furthermore, this technology in bio-medicine is the future of diagnosis and treatment of wounds because it is cheap, easy to apply and very effective in detecting common wound bacteria. Such technology could shade some green light in fighting microbial infections.

a, c, d, e are all applying about success strategies.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
