Q: Write down KVL equations for the below circuit.
Solution: in this circuit we have two loops one is on the right hand side i.e. BDCB.
and other is on the left hand side i.e. ABCA
By applying KVL equation for left hand loop ABCA
VR1 +VR2 - Vs =0
By applying KVL equation for right hand loop BDCB
20VR1 + VR3 - VR2= 0
