	Kirchhoff's circuit laws - QuickSeek Encyclopedia (Site not responding. Last check: 2007-10-09)
		Kirchhoff's circuit laws are a pair of laws that deal with the conservation of charge and energy in electrical circuits, and were first described in 1845 by Gustav Kirchhoff.
		This law has a subtlety in its interpretation, because in the presence of a changing magnetic field the electric field is not conservative and it cannot therefore define a pure scalar potential—the line integral of the electric field around the circuit is not zero.
		In order to "fix" Kirchhoff's voltage law for this case, an effective potential drop, or electromotive force (emf), is associated with the inductance of the circuit, exactly equal to the amount by which the line integral of the electric field is not zero by Faraday's law of induction.

	Kirchhoff's circuit laws - Gurupedia
		Kirchhoff's circuit laws are a pair of laws that deal with the conservation of charge and energy in electrical circuits, and were first described in
		At any point in an electrical circuit where charge density is not changing in time, the sum of currents flowing towards that point is equal to the sum of currents flowing away from that point.
		Kirchhoff's current law is equivalent to the statement that the divergence of the current is zero, true for time-invariant ρ, or always true if the displacement current is included with J.

	Kirchhoff's Laws
		Kirchhoff's laws deal with the conservation of energy and conservation of charge when applied to electrical circuits.
		Kirchhoff stated another set of laws, also known as Kirchhoff's laws, relating to radiation from incandescent objects, so to avoid ambiguity the electrical laws described in this article are sometimes known as Kirchhoff's rules.
		At any point in an electrical circuit, the sum of currents flowing towards that point is equal to the sum of currents flowing away from that point.

		Kirchhoff's first law states that the total current entering any junction in a circuit is the same as the total current leaving it.
		Kirchhoff's second law states that the sum of the potential drops across each resistance in any closed loop in a circuit is equal to the total electromotive force acting in that loop.
		The laws are equally applicable to DC and AC circuits.

	Kirchhoff's Voltage Law (KVL) - Divider Circuits And Kirchhoff's Laws
		Being a parallel circuit, the voltage across every resistor is the same as the supply voltage: 6 volts.
		All we have to do to comply with KVL is to begin and end at the same point in the circuit, tallying voltage drops and polarities as we go between the next and the last point.
		It is important to realize that neither approach is "wrong." In both cases, we arrive at the correct assessment of voltage between the two points, 3 and 4: point 3 is positive with respect to point 4, and the voltage between them is 32 volts.

	Applying the history of electricity in the classroom:a reconstruction of the concept of ‘Potential’ by Dr John Roche (Site not responding. Last check: 2007-10-09)
		On open circuit, this net internal voltage is zero and the external coulomb voltage is exactly equal in magnitude and circulatory sense to the voltage across the internal electromotive force.
		Hence Kirchhoff’s second network law follows: that the sum of the underlying e.m.f.s in any closed circuit is exactly equal to the sum of the net voltages in exactly the same circuit.
		In describing electric circuits it is clearly important to distinguish carefully between two interacting structures, namely, the auxiliary surface charge system which is conservative and which creates an absolute potential at every point of the circuit, and the electromotive forces which are not conservative and which do not contribute to the absolute potentials.
