Question

Consider the following circuit diagram.lf R1=R2=R3=R4=R5=3 ohm;find the equivalent resistance of the circuit.

Answer 1

SOLUTION

R2 and R3 are in the series so, R2,3

=) R2+ R3= 6 ohm

R2,3 is in parallel with R4 = 1/R2,3,4

=) 1/6+1/3+=

=) 3/6

=) 1/2

=) R2,3,4= 2ohm

=) R1, R5 & R2,3,4 in series so required

=) 3+3+3

=) 8ohm
