Question

find reading of ammeter in following circuit​

Answer 1

Answer:

2.5 ampere

Explanation:

as you can see in the circuit there are three resistors connected with the ammeter (one is parallel one 3 ohms)

resistence = 3+3=6

                  = 1\6 +1\3

                   =9\18 = 1\2(1\R) =R = 2

we know the formula V = IR (where v is volts and i is readings in ammeter and r is the resistence)

                                    I = V\R

                                    I = 5\2

                                    I = 2.5

therefore reading in the ammeter is 2.5Ampere
