Involving only the macroscopic quantities current, applied voltage and serial resistance this Volterra system can be handled with comparably little effort. Volterra integral equations models are formulated for a
Energy = voltage × charge.E=V×Q.Some like better to stick toEinstead toV, so do it. ForRtakeZ. The 12 most important Formulas: VoltageV=I×R=P/I= √(P×R) in volts V CurrentI=V/R=P/V= √(P/R) in amperes A ResistanceR=V/I=P/I2=V2/Pin ohms Ω PowerP=V×I= R ...
The processes are all interlocked in one system with multiple coupled pathways. Systems of this kind are characterized by feedback loops and inherent resistance to perturbations from a “set point,” although oscillations in internal conditions at various frequencies are the rule. The most important ...
The Hagen–Poiseuille equation describes the relationship between pressure, fluidic resistance and flow rate, analogous to voltage, resistance, and current, respectively, in Ohm’s law for electrical circuits (V=RI). From: Molecular Sensors and Nanodevices, 2014 ...
1.The method not only makes it usable and even easy to build the network nodevoltage equations when the circuit has VCVS and CCVS sources or voltage sources without resistance,but also is more practical than the modified node method when there are more equations,and even neutral elements in th...

I'm trying to set up an Excel worksheet that solves multiple equations for unknowns. For example I'd like to have equations for power and voltage drop across a resistor, and have Excel solve for Voltage, resistance and current, given enough variables input. I can do this on my HP49, ...
The power formula for a circuit with a voltage V and current I is P=V×I You can use Ohm's law to express either voltage or current in terms of the resistance R in the circuit: V = I × R. Doing so allows you to express power as a...
The circuit has a series and a shunt resistance. The trouble with this equation is that current depends on the voltage drop across components (V is the applied forward bias) and to evaluate that I need to use the relation V = IR (Ohm's Law). This makes it a recursive equation o...
The ratio between the applied voltage and external current density yields the ionic resistance of the mixed ionic-electronic conducting sample [24]: (59)Ri=Lσi=VoutIext However, eq. (59) can be applied only under restrictive conditions. Similar to determination of the partial electronic ...
