Answer:
Le calcul du courant se fait avec deux éléments : la tension et la valeur de la résistance. Courant (A) = tension (V) / résistance (Ohm) ce qui donne la formule I = U/R.

In a parallel connection, the equivalent resistance is the summation of the inverse of each individual resistances. It is mathematically expressed as 1/ Req = 1/10 +1/20 + 1/25 = 5.263 ohms. Also, the voltage across each resistor is equal to the input voltage, therefore I = 100 / 10 = 10 Amps. I hope this helped you.
        
             
        
        
        
Answer:
He requires 1 gram of mass.
Explanation:
The density is defined as:
 (1)
  (1)
Where m is the mass and V is the volume.
Then, m can be isolated from equation 1 in order to determine the mass.
 (2)
  (2)
 
  
 
  
Hence, he requires 1 gram of mass.
