Question

A set of three coils having resistances

10 Ω, 12 Ω and 15 Ω are connected in

parallel. This combination is connected

in series with series combination of three

coils of the same resistances. Calculate

the total resistance and current through

the circuit, if a battery of emf 4.1 Volt is

used for drawing current.​

Answer 1

Answer:total resistance will be

I will take as resistance as R so

1overR=1over10+1over12+1over15

in the end R a be 4 ohms
