The I-V graphs for two different electrical appliances ( P ) and ( Q ) are shown in diagram . If ( R_ p ) and ( R_ Q ) be the resistances of the devices, then

Options

  1. A( R_ p =R_ Q )
  2. B( R_ p >R_ Q )
  3. C( R_ p < R_ Q )
  4. D( R_ p = R_ Q 2 )

Correct answer

B. ( R_ p >R_ Q )

Step-by-step solution

By Ohm's law, ( V=I R I V = 1 R ) Thus, the slope of I-V graph is reciprocal of resistance. In the given diagram, Slope of ( Q> ) Slope of ( P ) [ array l 1 R₀ > 1 R_ p R_ p >R_ o array ]
