the Kirchoff law is two equilitis that deal with current and potential difference in the lumped element model in the electrical circuit

Each individual component in a circuit comes with its own current-voltage law. For resistors it’s called Ohm’s Law, v = i R. With just individual component laws there is not enough information to figure out voltages and currents. You need more info.
Kirchhoff’s Laws (KCL and KVL) represent the connectivity of a circuit. They place constraints on v and i. Example constraints: if two resistors are in series, their currents must be the same. If two elements are in parallel, their voltage must be the same.
With enough KCL and/or KVL equations, along with i-v equations for the components, you can find every current and every voltage in a circuit.
