When a series LED connection is in question, you will just need to replace the "LED forward voltage" with "total forward voltage" in the formula, by multiplying FV of each LED by the total number of LEDs in the series. Suppose there are 3 LEDs in series then this value becomes 3 x ...
We measure the potential difference in volts (which has units of joules per coulomb). The voltage in an electrical circuit controls the current in combination with the resistance. The voltage can be looked at as exerting an electric force on a positive charge (or a negative charge in the opp...
The core of the design and selection of tubular heat exchanger is to calculate the heat transfer area of the heat exchanger. To calculate the heat transfer area, it is necessary to know that K and Delta tm, K values are related to the structure, size and flow channel of the equipment. ...
You can also try online tools to calculate your BMR. These calculators usually involve inputting your sex, height, weight, and age to estimate your BMR. These calculators use the known formulas to make a guess based on your information. Knowing your BMR can be helpful when you are trying t...
A major drawback of using a voltage divider to calculate SOC is that it often produces inconsistent readings. A battery’s terminal voltage depends on the SOC as well as on load current, temperature, and age. Any variation in these three parameters can lead to ...
These parasites can easily transfer from tank to tank via fish, plants, decorations, or equipment. In this guide, I’ll explain what Ich is, how it infects your aquarium, how to identify its symptoms, and most importantly, how to treat it. With the right knowledge and action, you can ...
A static weight test is when you take a known/calibrated weight and hang it from your power meter. For power meters that support this type of test, they’ll display a given value and allow you to calculate whether that value is correct. For a dual-sided unit, you’d want the value ...
and current source together with the resistor in series. The fourth step is to add an equation so that we can measure voltage across the resistor. We can create that with a voltage source, resistor, and current source. We can then add an equation to calculate the voltage across the ...
To calculate the average power, it is necessary to follow the general procedure for averaging: the total power at each instant in the period of interest, divided by the time period, T. Therefore, the second step is to integrate P(t) over a full period. ...
How to Calculate the Linearly Weighted Moving Average (LWMA) Choose a lookback period. This is how many n values will be calculated into the LWMA. Calculate the linear weights for each period. This can be accomplished in a couple of ways. The easiest is to assign n as the weight for th...
