Answer:

Two resistors, R  

1

​  

andR  

2

​  

 are connected in parallel.  

We know,

R  

e

​  

 

1

​  

=  

R  

1

​  

 

1

​  

+  

R  

2

​  

 

1

​  

 

Then      R  

e

​  

=  

R  

1

​  

+R  

2

​  

 

R  

1

​  

R  

2

​  

 

​  

 

=  

50+100

50×100

​  

=  

150

5000

​  

=  

3

100

​  

   

Now, Parallel Connection error:

=  

(R  

1

​  

+R  

2

​  

)  

2

 

R  

1

2

​  

(dB)+R  

2

2

​  

(dA)

​  

 

=  

150  

2

 

50  

2

(3)+100  

2

(2)

​  

 

=  

150×150

7500+20000

​  

 

=  

9

11

​  

   

Relative Error =  

(100/3)

(11/9)

​  

=0.03666
