Question

What is the current I in the figure??

PLSSSS REQUIRES URGENTLY!!

WILL MARK AS BRAINLIEST!​

Answer 1

Explanation:

current is 0.1 A in the figure

Answer 2

Answer:

I = 0.1

Explanation:

I=V/R

there are 3 resistors each of 30 ohm.

2 of the resistors are in series connection, so their effective R= 60 ohm

So, the two 30 ohm resistors can be replaced by a 60 ohm resistor.

Now the 30 ohm and 60 ohm resistors are connected in parallel.

Effective R in parallel connection is:

1/R = 1/R1 + 1/R2

1/R = 1/30 + 1/60 , which gives

1/R = 3/60,

R= 60/3=20

Total effective resistance is 20 ohm.

Now, I = V/R

I = 2/20=0.1 A
