Question

33. The ammeter reading in the circuit below is
(1) 2A
(2) 3A
13) 6 A
(4) 5A​

Answer 1

Answer:

6 A

Explanation:

From ohms law,

V= I*R (I= total current, R= equivalent resistance)

V = 11*(1/1 +1/2 + 1/3)^-1

V = 11*6/11

V = 6

Now let i be current through 1 ohm resistor

i = V/r

i = 6/1

=6 ampere

Short cut method :

(R is equivalent resistance)

i = I * [ R/r ]. (I is total current)

(r is 1 ohm resistance)
