KCET2018PhysicsCurrent Electricity
Five identical resistors each of resistance ( R=1500 ) are connected to a ( 300 ) battery as shown in the circuit. The reading if the ideal ammeter ( A ) is
Options
- A( 1 5 A )
- B( 3 5 A )
- C( 2 5 A )
- D( 4 5 A )
Correct answer
B. ( 3 5 A )
Step-by-step solution
Given, ( R=1500 ; V=300 ~V ) Since the resistances are in parallel. The above circuit can be reduced to the circuit as follows: Thus, current through ammeter is ( I₂ ), given by [ I₂= V R = 300 R / 3 = 300 1500 / 3 = 300 500 = 3 5 ]
