Question

the resistance of circutor is 10 ohms and 20 ohms are connected in parallel in a circuit this is given to a battery e of 12 volt calculate the total current in the circuit​

Answer 1

Answer:

the total current in the circuit is 1.8A

Explanation:

resistance is in llel

so total resistance is(10*20)/(10+20) =200/30 R=20/3 ohm

V=12v

I=V/R

I=12/(20/3) = (12*3)/20 =18/10 =1.8A

the total current in the circuit is 1.8A

let's check ur current

V=IR

12= 1.8*(20/3)

12 = 0.6*20

12 =12

CORRECT YAAR

Answer 2

Answer:

When the resistances are connected in the parallel the equivalent resistance will be always less than the value of the lowest resistance in the parallel circuit.

The equivalent resistance in the parallel circuit can be calculated using the following formula.

1/R=1/R1+1/R2+1/R3

1/R= 1/10+1/20+1/30

1/R=(6+3+2)/60

1/R=11/60

R=60/11

R=5.45 Ohms
