Maximum Current Equation

Using these two ratings we can calculate another very important parameter which is the maximum current which can flow through the zener diode.

Maximum current equation. Since the initial voltage across the capacitor is zero vc 0 at t 0 the capacitor appears to be a short circuit to the external circuit and the maximum current flows through the circuit restricted only by the resistor r. Three phase power and current. What is the maximum amp for motor 5 5 kw 4 pole 3ph. Ma then the 2nd part of the question is what is the maximum e m f.

The product of the voltage and current is the apparent power and measured in va or kva. This calculator is based on simple ohm s law as we have already shared ohm s law p i v r calculator in which you can also calculate three phase current. If the formula is composed of relative cell addresses it will adjust the formula cell references relative to the current location. Enter part 2 answer.

The available solar radiation e ma varies depending on the time of the year and weather conditions. Which can also be expressed as. The relationship between kva and kw is the power factor pf. But we have designed this one especially for dc circuits as well as work for single phase ac circuits without power factor.

Nominal rated maximum kw p power out of a solar array of n modules each with maximum power of wp at stc is given by peak nominal power based on 1 kw m 2 radiation at stc. The power taken by a circuit single or three phase is measured in watts w or kw. The two ratings that are usually given with a zener diode is its voltage vz and power rating pzm in watts the amount of power that it can handle. Calculate the maximum current a 140 ohms 1 2 watt resistor can have flowing through it safely.

Which may be applied to the resistor above without causing overheating. Input current maximum power efficiency power factor minimum input voltage three phase maximum input current equation these input current calculations are for the worst case. The time required for the current flowing in the lr series circuit to reach its maximum steady state value is equivalent to about 5 time constants or 5τ. This time constant τ is measured by τ l r in seconds where r is the value of the resistor in ohms and l is the value of the inductor in henries.

However based on the average annual radiation for a location and taking into account the efficiency η of the cell. Power voltage current resistance p v i r calculator.
