Kirchhoff's Voltage Law and the Conservation of Energy
Gustav Kirchhoff's Voltage Law is the second of his fundamental laws we can use for circuit analysis. His voltage law states that for a closed loop series path the algebraic sum of all the voltages around any closed loop in a circuit is equal to zero.This is because a …
Milling Operations: Maintaining mill balance | ...
In engineering terms there must be mass balance, what goes into a machine or process must equal what comes out of a machine or process. The result of ring-around mass imbalance is fully appreciated and understood by most floor sweepers, utility persons and mill operators, and can be mathematically described by engineers using differential calculus.

P-N junction (no bias, short circuit) 1. Absorbed h excited e from valence to conduction, resulting in the creation of e-h pair 2. Under the influence of a bias voltage these carriers move through the material and induce a current in the external circuit. 3. For each electron-hole pair created, the result is an electron flowing in the circuit.
