Question

The reading of ammeter in the given circuit will
be

(1) 2A
(3) 4A
(2) 1A
(4) 3.5A​

Answer 1

Answer:

3)4a. I think

thanks for question

Answer 2

Answer:

The answer is 1Ampere

Explanation:

In the above circuit 4ohm and 4ohm resistors are in parallel combination.

so equivalent resistance is given by,

1/R = 1/4ohm + 1/4ohms

by simplification you get , 2ohms

Also the 15ohm , 15ohm and 15ohm resistor are in parallel combination

So ,

1/R = 1/15 + 1/15 + 1/15

by simplification you will get the answer as 5ohms.

Now the 3 ohms resistor, equivalent resistance of both the combination will come in series with each other.

So,

3ohm + 2ohm + 5 ohm = 10ohms

Now,

V = IR ( ohms law)

V=10v

R= 15ohms

So , by simplification

you will get 1Ampere .
