What is Electrical Power and How Can You Calculate it in Series and Parallel Circuits? Electrical power measures the rate of work represented in electrical circuits by the symbol “P” and the units of Watts (W). The total circuit power is additive for series, parallel, or any combination ...
How to Calculate Equivalent Resistance in Parallel? The combination of resistors in which the one end of all resistors is joined to a common point and the other end of all resistors is joined to another common point so that the number of resistors and number current paths are equal, it is ...
Personally, I NEVER calculate this directly. I always do an internet search for “voltage divider calculator” and plug in the numbers. It is a good idea to run this check to make sure the circuit is properly designed. All the other capacitors and diodes are used for filtering and protectio...
The best approach is to calculate the ON/OFF time of the transistor which yields maximum stable voltage across the output, meaning we need to make sure that the inductor is optimally switched such that it’s neither switched ON too quickly which might not allow it to discharge optimally, and...
If you have them in series (as most voltage dividers are) then the current is the same through both resistors I = V/(R1 + R2) = 5V/300 = 16.6mA Then, if you wanted to attach a load at the 3.3V voltage, you need to calculate the current through ...
I'm new to electronic circuit, I'm solving some problems in the book and come across this one, but I cannot calculate the value of Rs and Rp according to the info provided. Can someone help me with this, I solved equations using Thevenin but there is no solution for the value of tho...
Maybe your circuit is running off of 5V, yet you want only 3V to feed into a particular circuit element. How can you get the 5 volts into 3V? And you can do so with the correct resistor values in a voltage divider circuit. How do you calculate it?
The transistor that is chosen can really be any BJT NPN transistor. For this circuit, we choose the 2N3904 transistor. For a lot of the values of the components we actually compute, you won't be able to find those precise values. For example, below we calculate one of the resistors to...
A voltage divider is a simple circuit which reduces a large voltage into a smaller one. Using 2 resistors and an input voltage, we can create an output voltage that is a fraction of the input. Below you can see the formula that you need to use to calculate the resistors that you need...
The low efficiency in Figure 3 suggests a significant power dissipation across the LDO regulator, a result of the large input-to-output differential voltage and load current. Equation 1 shows how to calculate power dissipation across an LDO regulator....
