HI buddy! 
An integrated circuit(IC) is a semiconductor water on which thousands of tiny resistors, transistors are fabricated. 
Remember that an integrated circuit are the heart and brains of most circuits. They are the keystone of modern electronics. 
I hope this helps! 
        
             
        
        
        
Answer:
The magnitude of magnetic field at given point =  ×
 ×  T
 T
Explanation:
Given : 
Current passing through both wires = 5.0 A
Separation between both wires = 8.0 cm
We have to find magnetic field at a point which is 5 cm from any of wires.
From biot savert law, 
We know the magnetic field due to long parallel wires.
⇒ 
Where  magnetic field due to long wires,
 magnetic field due to long wires,  
  ,
,  perpendicular distance from wire to given point
 perpendicular distance from wire to given point
From any one wire  5 cm,
 5 cm,  3 cm
 3 cm
so we write,
∴ 
  
  ![B =\frac{ 4\pi \times10^{-7} \times5}{2\pi } [\frac{1}{0.03} + \frac{1}{0.05} ]](https://tex.z-dn.net/?f=B%20%3D%5Cfrac%7B%204%5Cpi%20%5Ctimes10%5E%7B-7%7D%20%5Ctimes5%7D%7B2%5Cpi%20%7D%20%5B%5Cfrac%7B1%7D%7B0.03%7D%20%2B%20%5Cfrac%7B1%7D%7B0.05%7D%20%5D)
  
Therefore, the magnitude of magnetic field at given point = 
 
        
             
        
        
        
Option c) 1.5 V
Explanation:
<em>As the circuit is build in series first we will find the current passing through the complete circuit. Current stays the same in each element is the series cirucuit, however, the voltage is different.</em>
Voltage is given by the following formula:
V = IR
<em>Because we have to find current through whole circuit, we will first find resistance of the whole circuit.</em>
Equivalent Resistance R(eq): R1 + R2 = 60 + 60 = 120 ohm
Current passing through whole circuit be: 
 = 0.025
 = 0.025
Now we will find out the voltage between C and D:
Current stays the same in series circuit: I = 0.025 c
Resistance between C and D is, R = 60 ohm
Voltage becomes, V = IR = 0.025 * 60 = 1.5 V
