We have here what is known as parallel combination of resistors.
Using the relation:

And then we can turn take the inverse to get the effective resistance.
Where r is the magnitude of the resistance offered by each resistor.
In this case we have, 
(every term has an mho in the end) 

To ger effective resistance take the inverse:
we get, 

The potential difference is of 9V.
So the current flowing using ohm's law,
V = IR 
will be, 0.0139 Amperes.
 
        
        
        
Answer:
1.87 A
Explanation:
τ = mean time between collisions for electrons = 2.5 x 10⁻¹⁴ s
d = diameter of copper wire = 2 mm = 2 x 10⁻³ m 
Area of cross-section of copper wire is given as 
A = (0.25) πd²
A = (0.25) (3.14) (2 x 10⁻³)²
A = 3.14 x 10⁻⁶ m²
E = magnitude of electric field = 0.01 V/m 
e = magnitude of charge on electron = 1.6 x 10⁻¹⁹ C 
m = mass of electron = 9.1 x 10⁻³¹ kg 
n = number density of free electrons in copper = 8.47 x 10²² cm⁻³ = 8.47 x 10²⁸ m⁻³ 
 = magnitude of current
 = magnitude of current 
magnitude of current is given as 


 = 1.87 A
  = 1.87 A

Answer:
The correct option is;
c. 22.6
Explanation:
The given parameters are;
The hypotenuse of the vector = 32
The angle of the vector = 45°
Therefore, the vector component in the y-axis is given as follows;

Substituting the values from the question gives;

The vector component in the y-axis,  , is approximately 22.6.
, is approximately 22.6.
