Question

to get the resistance make the relation between the electric current and potential difference of r1 r2 r3 connected in series with electric circuit​

Answer 1

Hey mate here's your answer:-

We have a circuit with 3 resistance, a battery, a an electronic device connected in circuit.

V=I.R(by the om'slaw)

in circuit there's resistance is R1 R2 R3

and current is " I"

and potential difference is

V1 V2 V3

therefore-

V=V1+V2+V3

V=IR1+IR2+IR3 (V=IR)

IR=I(R1+R2+R3)

R=R1+R2+R3(Hence proved)
