Question

Calculate the total current in the circuit.a)20Ab)11.42Ac)12Ad)15ACorrect answer is option 'B'. Can you explain this answer?

Answer

The total resistance will be 10.5 . So I =V/R i.e 120/10.5 = 11.43A

Answer

Answer

i am also getting equivalent resistance is 10.5

Answer

3×3/(3+3)=1.5
1.5+4+5=10.5
I=120/10.5=11.42

Answer

11.43 is correct answer

Answer

1 ohm and 2 ohm are in series ....equivalent is 3 ohm which is in parallel with 3 ohm so equivalent is 1.5 ohm, is in series with 4 and 5 ohm so total resistance is 10 ohm so by equation I = V/R....we can find the current I = 10 Amp.

Answer

In explanation they have added 3 4 5 ohm resistors that yields equivalent resistance of 12 ohm which is wrong!

Answer

10A

Answer

The total resistance will be 10.5
then I= 120/10.5 =11.43 A

Answer

C

Answer

11.43

Answer

Answer

12.8amp

Answer

11.42

Answer

11.4
total resistance =10.5
I=120÷10.5=11.4

Answer

As total resistance is 10.5 ohms we get  total current approximately 12A

Answer

Actually 11.42 is the correct answer, I agreed

Answer

By using Khirchof low

i1=i2+i3....... eq1

120-5i1-i2-2i2-3i3-4i1=0
120-9i1-3i2-3i3=0
120-9i1-3(i2+i3) =0
from eq 1
120-9i1-3i1=0
120-12i1=0
12i1=120
i1=10A

Answer

15

Answer

Given V =120,
first we are cal. total R , and the total R =10.5
now as we know I=V/R
so,
I=120/10.5
and
I=11.4

Answer

1 and 2 ohm resistors are in series so 3 ohms ,3 ohms and 3 ohms resistors are in parallel so 1.5 ohm and 4 ,1.5 , 5 ohm resistors are in series so 10.5 ohm. finally 120/10.5=11.42A.

Answer

2+1=3 then 1/3 +1/3=3/2 then 3/2+4+5=21/2 then 120*2/21 ~12😊

Answer

11.4 correct answer

Answer

1and2in series it solutions is 3
and3 is parallel with 3 it solutions is 1.5
then 4,5 and 1.5 are in series it solutions is 10.5
then V=IR se I=V/R
120/10.5=11.42
