Question

# In the figure ammeter reads $$I_1$$ and voltmeter reads $$V_1$$. Similarly in figure 2, ammeter reads $$I_2$$ and voltmeter reads $$V_2$$. Then which of the statements are true?

A
V1>V2 and I1>I2
B
V1>V2and I1<I2
C
V1>I1and V2>I2
D
V1=V2

Solution

## The correct option is B $$V_1>V_2$$and $$I_1<I_2$$In Fig 1     $${ V }_{ 1 }={ I }_{ 1 }({ R }_{ 1 }+{ R }_{ 2 })\\ { I }_{ 1 }=\frac { { V }_{ 1 } }{ { R }_{ 1 }+{ R }_{ 2 } }$$In Fig 2  $${ V }_{ 2 }={ I }_{ 2 }{ R }_{ 1 }={ I }_{ 2 }{ R }_{ 2 }\\ { I }_{ 2 }=\frac { { V }_{ 2 } }{ { R }_{ 1 } } +\frac { { V }_{ 2 } }{ { R }_{ 2 } }$$$${ I }_{ 2 }={ V }_{ 2 }\left( \frac { 1 }{ { R }_{ 1 } } +\frac { 1 }{ { R }_{ 2 } } \right)$$By equatimg Fig1 value and Fig 2 value   $${ V }_{ 1 }>{ V }_{ 2 }$$And  $$I_{ 2 }>{ I }_{ 1 }$$Option (B) is correct option.Physics
