2. Kirchhoff's circuit laws - Wikipedia

   en.wikipedia.org/wiki/Kirchhoff's_circuit_laws

   The current entering any junction is equal to the current leaving that junction. i 2 + i 3 = i 1 + i 4. This law, also called Kirchhoff's first law, or Kirchhoff's junction rule, states that, for any node (junction) in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node; or equivalently:

3. Ohm's law - Wikipedia

   en.wikipedia.org/wiki/Ohm's_law

   Ohm's law states that the electric current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, [1] one arrives at the three mathematical equations used to describe this relationship: [2] where I is the current through the conductor, V ...

4. Worksheet - Wikipedia

   en.wikipedia.org/wiki/Worksheet

   In accounting, a worksheet is, or was, a sheet of ruled paper with rows and columns on which an accountant could record information or perform calculations. These are often called columnar pads, and typically green-tinted. In computing, spreadsheet software presents, on a computer monitor, a user interface that resembles one or more paper ...

5. Series and parallel circuits - Wikipedia

   en.wikipedia.org/wiki/Series_and_parallel_circuits

   Series and parallel circuits. A series circuit with a voltage source (such as a battery, or in this case a cell) and three resistance units. Two-terminal components and electrical networks can be connected in series or parallel. The resulting electrical network will have two terminals, and itself can participate in a series or parallel topology.

6. Current divider - Wikipedia

   en.wikipedia.org/wiki/Current_divider

   In electronics, a current divider is a simple linear circuit that produces an output current (IX) that is a fraction of its input current (IT). Current division refers to the splitting of current between the branches of the divider. The currents in the various branches of such a circuit will always divide in such a way as to minimize the total ...

7. Integrated mathematics - Wikipedia

   en.wikipedia.org/wiki/Integrated_mathematics

   Integrated mathematics is the term used in the United States to describe the style of mathematics education which integrates many topics or strands of mathematics throughout each year of secondary school. Each math course in secondary school covers topics in algebra, geometry, trigonometry and functions. Nearly all countries throughout the ...
