Determining the resistor value for lighting LEDs is simple and straightforward, but we must take into consideration the color of the LED as well as the wattage rating of the required resistor, and the number of LEDs in the circuit. We hope reading How to Calculate Resistor Value for LED Ligh...
Calculate the equivalent resistance for the circuit, if it is part of a larger network. A group of resistors in parallel can be replaced by a single equivalent resistance Req, which simplifies calculations when trying to obtain network parameters. Now instead of a group of resistors in parallel ...
How do you calculate equivalent resistance? Explain. Resistance:Resistance measures the ability of a given object to resist or inhibit electric current flow. An electrical circuit has specially-made components to control the flow of current called resistors. When multiple resistors are connected ...
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} {/eq}. Substituting values for the resistors, we get: $$\dfrac{1}{R_{eq}} = \dfrac{1}{150\ \rm{\Omega}} + \d...

Next, connect the calculated value of resistors as discussed in the previous section to any one of the free ends of each series, you can connect the resistor at the positive end of the string or the negative end, the position doesn't matter because the resistor just needs to be in line...
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 ...
Try to calculate these resistors' values. Answers are on the next step. Step 5: Answers The first one is : 11000 = 11k ohms The second one is : 1000 = 1k ohms The both are with gold color for the tolerance ,it means 5%.
To calculate the total overall resistance of a number of resistors connected in this way you add up the individual resistances. This is done using the following formula: Rtotal = R1 + R2 +R3 and so on. Example: To calculate the total resistance for these three resistors in series. ...
How to measure low resistances (Resistance Measurement Methods) - The resistances of the values of less than or equal to 1 Ω are classified as low resistances. For example, the resistances of armatures and series windings of large machines, ammeter shun
