Question

please solve that question so i know u are brilliant​

Answer 1

Answer:

12Ampere is the right anawer

Explanation:

They all are in parallel combination so first I find equivalent resistance and then apply ohm's law.

Answer 2

Answer:

Explanation:

LET R₁ = 10 OHMS

      R₂ = 5 OHMS

      R₃ = 10 OHMS

IN THIS CIRCUIT R₁,R₂,R₃ ARE IN PARALLEL  CONNECTION

1/ R NET₁ = 1/R₁+1/R₂

R NET₁ = R₁R₂/(R₁+R₂)

           = 10*5/(10+5)

           = 50/15

           = 10/3 OHMS.

THIS R NET₁ IS IN PARALLEL WITH R₃

1/R NET₂  = 1/R NET₁+1/R₃

R NET₂ = R NET₁*R₃/(R NET₁+R₃)

R NET₂ = (10/3)*10/(10/3+10)

R NET₂ = 10/4 OHMS.

NET RESISTANCE OF THE CIRCUIT ,R = 10/4 OHMS

VOLTAGE , V = 30 VOLTS

CURRENT,I = ?

ACCORDING TO OHMS LAW ,

V  = I*R

30 = I*10/4

I = 30*4/10

I = 12 A.

HOPE THIS HELPS.
