Calculate equivalent resistance of two resistors `R_(1) and R_(2)` in parallel where, `R_(1) = (6+-0.2)`ohm and ` R_2 = (3+-0.1)ohm`

If equivalent resistances of R _(1) and R _(2) in series and parallel be r _(1) and r _(2) respectively, then (R _(1))/( R _(2)) equals

If resistors of resistance R_(1) and R_(2) are connected in parallel,then resultant resistance is "

The combined resistance of two resistors R_1 and R_@ (R_1,R_2>0) is given by 1/R= 1/R_1 + 1/R_2 . If R_1 + R_2 =C (a constant), show that maximum resistance R is obtained by choosing R_1 = R_2

The combined resistance of two resistors R_(1) and R_(1)" is given by "1/R=1/R_(1)+1/R_(2)," where "R_(1)+R_(2) = C (constant ), show that R is maximum when R_(1)= R_(2) .

Write the expressions for the equivalent resistance R of three resistors R_1, R_2 , and R_3 joined in (a) parallel, and (b) series.

Two resistors of resistances R_(1)=100 pm 3 ohm and R_(2)=200 pm 4 ohm are connected (a) in series, (b) in parallel. Find the equivalent resistance of the (a) series combination, (b) parallel combination. Use for (a) the relation R=R_(1)+R_(2) and for (b) 1/(R')=1/R_(1)+1/R_(2) and (Delta R')/R'^(2)=(Delta R_(1))/R_(1)^(2)+(Delta R_(2))/R_(2)^(2)
