Question

Three resistors of 15 ohms each are connected to form the sides of a triangle .The equivalent resistance across any two points of the triangle will be.​

Answer 1

Answer:To calculate resistance between A and B,we can treat resistors between BC and AB to be in series,

There equivalent hence is,

R  

′

=R  

BC

​  

+R  

AC

​  

⟹R  

′

=60+100=160Ω

Now this equivalent resistor is in parallel with R  

AB

​  

.

Equivalent of R  

′

 and  R  

AB

​  

 can be calculated using formula,

R  

EQ

​  

=  

R  

AB

​  

+R  

′

 

R  

′

R  

AB

​  

 

​  

⟹R  

EQ

​  

=  

160+40

160×40

​  

=32Ω
