Question

What is the equivalent resistance of three $1000\Omega$ resistors in series?

• A. $1000\Omega$
  
• B. $3000\Omega$
  
• C. $2000\Omega$
  
• D. $1100\Omega$
  

Answer 1

The correct option is B $3000\Omega$

Given : $3$ resistors of resistance $R=1000\Omega$

Equivalent resistance in series combinationis given by,

$R_{eq}=R_1+R_2+R_3$

$R_{eq}=R+R+R=3R=3000\Omega$
