Schools a business. They want us to fail.

Howd you do anyway ?

@@KAVORKA.KIINGG Actually working on my finals right now but averaging an A.

@@mitchellarmyguy2515 hells yeah buddy!! Hopefully Im there in 2 months .

Becouz ur professor is the student of my professor...🤫

It really do be like that starting out

Hi I m from india

u look gorgeous

Do take look at this also. What is a resistor? How does current branch in a network of resistors? How does it "know" how much should flow in each branch? While some detail is given in science and engineering courses about conductors, insulators and semiconductors, resistance is described in several ways. Examples include i. The restriction to the flow of electrons. ii. The difficulty in moving electrical current through a conductor to which voltage is applied. iii. a circuit element which dissipates energy in the form of heat . More appropriate description for a resistor would be the property of a conductor which determines the current produced by a given difference of potential. This makes us remember that a resistor is a conductor first. And, there is reason to say that superconductive wires dont obey ohm's law. So all conductors are resistive, though not superconductors. Resistors are used in circuits to regulate the strengths of currents either by reducing the diameter of conductors or introducing more obstacles or lattice imperfections to reduce the strength of current. The current branches in a parallel network by an elaborate rearrangement of surface charge. For more details about resistance, how current branches in a parallel circuit and ohm's law consult the following videos, articles and books. What is current ? What is voltage ? A working definition for current in conductors like metal wires is "the start-stop motion of millions and millions of conduction band electrons everywhere within with a drift superimposed". In circuits, voltage is due to surface charges. Consider a simple circuit comprising a battery, two wires and a resistor. The e.m.f of the battery is due to separation of positive from negative charges which produces an e.m.f across its terminals and a pattern of electric field surrounding them, not exactly but like a dipole. An electric field is there in the wires and in the resistor; powerful electric field and uniform within the resistor, weak and uniform within the wires. The field is set up by a tiny amount of surface charge with a steep gradient on the resistor and not so steep a gradient on the wires. It is the electric field E created by the surface charges sourced from the battery, which produces a force causing the mobile electrons to acquire a drift velocity v = μE, where μ is the mobility which is a number representing the freedom of movement of the electron in the lattice. This results in a current density J = σE, where σ is the conductivity of the wire or material of resistor and E is the electric field in the wire if considering wire and is the field in the resistor when considering the resistor. The p.d. or voltage across the resistor is the integral of a constant powerful field along its length. The p.d. or voltage across the wires is the integral of a constant but weak field along its length. Voltage is entirely because of the surface charges. Electrostatics and circuits belong to one science and not two, that of electricity and magnetism.

Hi I m from india

You have to think about the path the current (I) runs. It starts off going through the 25Ω, then it splits between the 8Ω and the 30Ω. The current becomes smaller at the 30Ω and 50Ω than it was at the 25Ω. Because of that "node" splitting the current you cannot add the 25 30, and 50Ω. Same idea goes for the next loop. You cannot add different resistors together when they have different currents. Thus in this equation you have to simplify the parallel resistors (which means simplifying the series at the far right).

And the total current

Because current is deviding just after the 8k resistance
