resistance
Opposition that a material or electrical circuit offers to the flow of electric current. It is the property of a circuit that transforms electrical energy into heat energy as it opposes the flow of current. The resistance R, the electromotive force or voltage V, and the current I are related by Ohm's law. The resistance of an electrical conductor generally increases with increasing temperature and is utilized in devices such as lamps and heaters. The ohm (Ω) is the common unit of electrical resistance; one ohm is equal to one volt (see electromotive force) per ampere.

In general, the path that lightning takes will minimize the resistance.

The call "Wheatstone" traditionally refers to a 4 resistor bridge. there are various different varieties of bridges that are no longer Wheatstones. even however, all real bridges have 4 considerable impedances. those impedances may well be resistors, inductors, or capacitors. case in point, a capacitance bridge is constituted of two inductors, in one in each of those a ratio transformer, and a pair of capacitors. One precision adjustable capacitor and one unknown capacitor. Why is it continuously 4 impedances? A bridge is a pair of voltage dividers with each divider being constituted of two impedances. the purpose of the bridge is to subtract 2 almost equivalent great voltages (the outputs of the two dividers) to extract a small sign. frequently, one divider is adjusted with the intention to 0 the version sign.

Electrical resistance?
Well elctron gets in, hits nerby electron which hits some else .....
And the electrons are coming in and from other side going out (with slow velocity).
So the electron strike and loose energy in form of heat (etc)
THis loss of heat is attributed to resistance as it is dependent of amount of current flowing and the material.

No defeat, never surrender, that's the principal I live by.
Oh that's not what you meant? sorry, I'm not a physicist.
