Explanation:

two laws concerning electric networks in which steady currents are flowing. The first law states that the algebraic sum of the currents in all the conductors that meet in a point is zero. The second law states that the algebraic sum of the products of current and resistance in each part of any closed path in a network is equal to the algebraic sum of the electromotive forces in the path.

<font color="pink"><i>Kirchhoff's Current Law (KCL): This is also known as the first law, point rule or junction rule and is the principle of conservation of electric charge. It states that the amount of current flowing into a node or junction is equal to the sum of the currents flowing out of it.

Kirchhoff's voltage law states that the algebraic sum of the potential differences in any loop must be equal to zero as: ΣV = 0. Since the two resistors, R1 and R2 are wired together in a series connection, they are both part of the same loop so the same current must flow through each resistor.

Kirchhoff Voltage Law states that ''The algebraic sum of all voltages (source voltage and voltage drops) is equal to zero around a close path''. In the above circuit R1, R2 and R3 are three resistors connected in series across a voltage source V.

Kirchoff's First Law. Kirchoff got himself a huge name in physics by simply applying two principles of physics to electrical circuits. This is the first: At any junction in a circuit, the sum of the currents arriving at the junction = the sum of the currents leaving the junction. In other words - charge is conserved.

Kirchoff's Second Law. Kirchhoff's Second Law states that the “net electromotive force around a closed circuit loop is equal to the sum of potential drops around the loop”. ... This law manages the voltage drops at different branches in an electrical circuit. Consider one point on a closed loop in an electrical circuit.

Kirchhoff's Laws are: A hot solid, liquid or gas, under high pressure, gives off a continuous spectrum. A hot gas under low pressure produces a bright-line or emission line spectrum. A dark line or absorption line spectrum is seen when a source of a continuous spectrum is viewed behind a cool gas under pressure.
