Young electronic hobbyists and enthusiasts are often confused and wonder how to calculate LED and its resistor in a circuit, since they find it difficult to optimize voltage and current through the group of LEDs, required to maintain an optimum brightness. Why we need to Calculate LEDs Designing...
How to Calculate the Equivalent Resistance In a Parallel Circuit Step 1: List the value of each resistor in the circuit. Step 2: Calculate the equivalent resistance using the equation {eq}\dfrac{1}{R_{eq}} = \dfrac{1}{R_1} + \dfrac{1}{R_2} + ... + \dfrac{1}{R_N} {/...
Moreover since the collectors of the transistors are supposed to be in parallel and joined with each other, the use of mica isolators no longer become essential and makes things much convenient as the body of the transistors get connected in parallel through their heatsink metal itself. It's ...
Calculate the total resistance of the parallel circuit by using the equation 1/Rtotal = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn. This equation states that by adding the inverses of all of the individual resistors, you will get the inverse of the total resistance. Pretend that you have t...
To calculate output voltage from a circuit, use Ohm's law. Voltage is measured in volts, current is measured in amps and the resistance is measured in ohms. The formula needed is V = I x R. You can use this formula in both parallel and series circuits.
An amp is the unit used to measure current in an electrical system. There are several ways to calculate amperage using other units of electricity, including watts, volts, and ohms. In this article, we’ll look at what an amp is, the formula to calculate amps, and why knowing how to de...
However, when the internal resistance is not enough to measure larger currents, an external configuration is needed. To measure larger currents, you can place a precision resistor called a shunt in parallel with the meter. Most of the current flows through the shunt, and only a small fraction...
The resistance in parallel circuits can be thought of as adding another road to allow traffic to flow. When we add another road, traffic can flow more quickly, decreasing the total resistance. No matter how high the resistance in the new parallel, total resistance will always be lower....
Hence, my battery can theoretically discharge the current as high as 4.2V/0.24=17.5A (short circuit maximum current at fully charged state) but it is not good to do so. If higher current output is desired, more batteries should be connected in parallel to reduce the overall internal resistan...
