What is the effective resistance between BC if the value of each resistor, R, is 120 Ω?
Here, for the resistance between B and C
for R and R in series
RCD = 2R
for 2R and R in parallel
1/Req = 1/(2R) + 1/R
Req = 2R/3
NOw, R and Req in series
R3 = 2R/3 + R = 5R/3
for R3 , 2R , R in parallel
1/Req = 1/(5R/3) + 1/(2R) + 1/R
1/Req = 1/(5 * 120/5) + 1/(2 * 120) + 1/120
Req = 48 Ohm
the effective resistance is 48 Ohm
