Question

9) A) State the laws based on conservation of charge and energy? B) In a
circuit 60v battery three resistors R1=20ohms, R2=40ohms, R3=Xohms are
connected in series. If 2 amperes current flows in the circuit, find the resistance
R3 by using Kirchhoff's loop law?​

Answer 1

I= 2A V=60V R3=?

R= V/I

R= 60/2

R3= 30ohm

R1=20 ohm R2=40ohm R3=30 ohm

Rs= R1+R2+R3

= 20+40+30

Rs= 90 ohm

Ihope it may be useful.
