Consider the combination of resistors shown in the figure below.

a) find the equivalent resistance between point a and b.

(b) if a voltage of 28.8 v is applied between points a and b, find the current in each resistor.

12 ω a

6 ω a

5 ω a

4 ω a

8 ω a

Part a)

Total equivalent resistance = 11.67 Ω

(answer and working is provided in the attached file)

Part b)

Vт = Iт × Rт

28.8 = Iт  ×  11.67

Iт = 28.8/11.67

Iт = 2.47 A

Current in 12Ω :

12+6 = 18 Ω

= 12/18 × 2.47

= 1.65 A

Current in 6Ω :

= 6/18 × 2.47

= 0.82 A

Current in 5Ω :

= 2.47 A (as the current in a series circuit will be equal to the total current)

Current in 4Ω :

4+8 = 12 Ω

= 4/12 × 2.47

= 0.82 A

Current in 8Ω :

= 8/12 × 2.47

= 1.65 A

it is because acrylic blanket have acrylic textile fiber

explanation:

its is better than wool blanket

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
