A Combination Consists of Three Resistors in Series. Four Similar Sets Are Connected in Parallel. If The Resistance of Each Resistor is 2 Ohm, Find the Resistance of the Combination. - Physics
A combination consists of three resistors in series. Four similar sets are connected in parallel. If the resistance of each resistor is 2 ohm, find the resistance of the combination.
Resistance of each set:
1r = 2 + 2 + 2 = 6 ohm
2r = 2 + 2 + 2 = 6 ohm
3r = 2 + 2 + 2 = 6 ohm
4r = 2 + 2 + 2 = 6 ohm
Now these resistances are arranged in parallel :
`r=6/4=1.5 ohm `
Concept: System of Resistors - Resistances in Parallel
