The Nernst equation is E = ((-2.3RT)/zF)*(log10 [Ci/Co])
E = equilibrium potential (mV)
z = charge on the ion
(2.3RT)/F = constant (60mV at 37C)
Ci = intracellular concentration
Co = extracellular concentration
The Nernst equation is important because it shows what the equilibrium potential would be for one ion.
E.g. The resting membrane potential is normally ~70mV. So during an action potential Na channels open their gates briefly and Na rush inside the cell. Na is ionized and carries a positive charge. So when Na rushes into the cell it makes the inside of the cell more positive. If you were to break off the gate and allow Na to move freely back and forth, the Nernst equation shows us that the equilibrium point for Na is ~+65mV.

Measure AC voltage with multimeter. It is easiest way to check how big ripple is. There is no way to 'calculate' value.
One way to determine current is to measure it, with an ammeter. Another way is to calculate it using Ohm's law: current = voltage / resistance.
One way to calculate current is using ohms law; current equals voltage divided by resistance or: I=V/R Where I is current, V is voltage and R is resistance.
Kw can be calculated from volts be using the formula p=(voltage)square/resistance*1000
An ammeter measures amperage not voltage.
A: by using thevenin theorem
You calculate the coordinates using a fraction!
i dont know that's why I'm asking
The formula you are looking for is - phase voltage/1.73 = phase to neutral voltage.
Find (or calculate) the equation of the line. Select any value of x. Calculate the corresponding value for y using the equation. Then (x, y) is a point on the same line.
yes we can calculate it by using trigonometric equation (by finding tan θ).
by using the equation k=LN(present#/pats #)/(t2-t1).
The two most important ratings for an electrical heater are its rated power and its rated voltage, and these will be printed on a 'nameplate' fixed somewhere on the heater (e.g. '3 kW at 230 V').For the heater to operate at its rated power, it must be subject to its rated voltage. In the above example, the heater will only operate at 3 kW if it is supplied with 230 V.If you know the heater's power (P) and its voltage (U), then you can calculate the rated current (I) it will draw from the supply, using the equation: I = P/U.You can also determine its resistance (R), using the equation R = U2/P.
You need to know the temperature of the reference junction and the voltage difference between the reference and sensing junctions. First, you convert the reference temperature to a voltage using the reverse equation or table for your thermocouple type. Then you sum that voltage with the measured voltage. Finally, you convert the summed voltage back to a temperature using the equation or table for the thermocouple type you are using. If the reference junction is at zero degrees C, you can skip the reference summing part. Before computer processing was easy and cheap, the reference junction was often kept in an ice water bath for that reason.
Using Ohm's law, you can find voltage if power is given. The equation needed to solve for power is P(Power)= Voltage(E) x Current(I). Ohm's Law describes the relationship between resistance, current, power, and voltage.

Yes. You can calculate the two roots of a quadratic equation by using the quadratic formula, and because there are square roots on the quadratic formula, and if the radicand is not a perfect square, so the answer to that equation has decimal.
