Question

krichhfors law to verify first law n second law​

Answer 1

Kirchoff's first law:

at any junction in a circuit, the sum of the currents arriving at the junction = the sum of the currents leaving the junction.

Current in = Current out

I1=I2+I3+I4

Kirchoff's second law:

in any loop (path) around the circuit,the sum of emfs = the sum of the pds.

Energy in =Energy out

emf = pd1+pd2+pd3+pd4
