Question

Resistance are given as R1=10 ,R2=20 &R3=30. Calculate the effective resistance when they Are connected in series also calculate the current when the combination is connected to the 6 volt

Answer 1

in series all r added
r=r1+r2+r3
r=60
i=v÷r
i=6÷60
I=0.1

Answer 2

Rs = R1 + R2 + R3

Rs = 10 + 20 + 30 = 60 Ohm

E = 6 V

Current = E/R =  6/60

= 0.1 A

Effective resistance = 60 Ohm

Current = 0.1 A
