Question

this is the numerical of physics...
plz hlp​

Answer 1

total resistance along circuit = 10 +5+15 = 30 ohm

total potential = 30 v

current along circuit = 30/30= 1ampere

Answer 2

series means add all the three directly

Resistance(series)=5+10+15=30

v=30v

V=IR

30=I×30

30/30=1A

I=1A
