1.	Establish a relationship to determine the equivalent resistance R of a combination of three resistors having resistances R_1, R_2 and R_3 connected in series. (b) Calculate the equivalent resistance R of a combination of three resistors of 2 Omega, 3 Omega and 6 Omega joined in parallel.
Answer» Solution :(B) Here `R_1=2 OMEGA, R_2=3 Omega and R_3=6 Omega` The equivalent RESISTANCE R for parallel COMBINATION of RESISTORS will be `1/R=1/R_1+1/R_2=1/2+1/3+1/6=1/1 implies R=1 Omega`
