Question

two resistance 3 ohm and 7 ohms are connected in parallel the total current through the resistors is 15 ampere then the current through the resistors are​

Answer 1

Answer:

31.5

Explanation:

Apply V=IR

and put all values....

Answer 2

IR1 = 4.5 A   ;  IR2 = 10.5 A .

Given:

• Two resistance R1 = 3 ohm and  R2 = 7 ohms.
• The total current through the resistors  I = 15 A.

To Find:

• The current through the resistors R1 & R2 ?

Solution:

The current flows through the resistor R1 is   $I_{R1}$ = I (R2 / R1+R2)

The current flows through the resistor R2 is  $I_{R2}$  = I (R2 / R1+R2)

Application with the values,

R1 = 3 Ω, R2 = 7 Ω, I = 15 A

IR1 = $I_{3ohms}$ =  15 × (3 / 10)

                  =  15 (0.3)

                  =   4.5 A

IR2 = $I_{7ohms}$ = 15 × (7 / 10)

                   =  15 (0.7)

                   =   10.5 A

Hence the current through the resistors R1 & R2 are​ :

I R1  = 4.5 A

I R2 = 10.5 A
