1 ) If we want to decrease the resistance , so we put resistors in . . . . . . . . . . . . ,

Choose single option from these following : -

A ) series ,                                                       B ) parallel ,

C ) both will show same resistance ,               D ) None of these ,

Correct Answer : -  B ) parallel ,

 

2 ) A thermistor with ( + ve ) temperature coefficient , if we increase the temperature , so resistance will . . . . . . . . . . . . ,  

Choose single option from these following : -

A ) increase ,                                           B ) decrease ,

C ) remain same ,                                    D ) None of these ,

Correct Answer : -  A ) increase ,

A thermistor with ( + ve ) temperature coefficient , if we increase the temperature , so resistance will also increase and vice versa .

 

3 ) A thermistor with ( - ve ) temperature coefficient , if we increase the temperature , so resistance will . . . . . . . . . . . . . . ,

Choose single option from these following : -

A ) increase ,                                           B ) decrease ,

C ) remain same ,                                    D ) None of these ,

Correct Answer : -  B ) decrease ,

 

4 ) Ω ( ohm ) = . . . . . . . . .?

A ) V / A ,                                                 B ) A / V  ,

C ) W / A ,                                                D ) None of these ,

Correct Answer : -   A ) V / A ,

Unit of resistance is ohm and which is equals to volt / ampere : -    Ω = V / A .

And unit of resistivity is ohm – meter .
