To calculate the voltage across an inductor, the formula is: All you have to know to calculate the voltage across the inductor isL, the Inductance of the Inductor which is expressed in units, Henry, and the derivative of the current going through the inductor. Example If the current going t...
How to Calculate IRMS The current in an alternating current circuit varies continuously in direction and magnitude. Calculations involving the current don't therefore consider the current at any single instant. They instead use the root mean square current, a value that takes into account the curren...

You measure 45.7 mA through an inductor with a voltage of 2.12 V across it. What reactance does it offer? A 21.0-mH inductor has a reactance of 2.00 k?. (a) What is the frequency of the ac current that passes through the inductor? b) What is the capacitance of a capacitor that has...
You can calculate the amount of wire of width W needed to make a coil of radius R and length L by using the formula 2?R x (L/W). This formula is equivalent to the circumference each loop of the wire makes times the number of such loops in the coil. This formula is, however, a...
Work from one corner horizontally across to the other, then forward evenly towards the front of the device. Stop at intervals to check for tears on the outside. If tears do occur it's not the end of the world - if you stop immediately and use the knife to peel the glue off, the ...
Before you begin, you’ll want to get an idea of how muchoutput poweryou want from the amplifier. You’ll also need to know theimpedanceof your speakers and theinput voltageof your audio source. Be sure to check the TDA2050’s datasheet to find the absolute maximum ratings for these pa...
When the lamp first turns on, the path of least resistance is through the bypass circuit, and across thestarter switch. In this circuit, the current passes through the electrodes on both ends of the tube. These electrodes are simplefilaments, like you would find in an incandescent light bulb...
An ideal solenoid would be infinitely long with tightly packed coils, where each coil falls into a plane perpendicular to its central axis. In this solenoid, the generated magnetic field of the electric current is concentrated inside the solenoid coil. The intensity of the magnetic field outside...
where I is the current flowing through the circuit, V is the electric potential difference across the battery, and R is the resistance of the resistor(s) in the circuit. What is Current? Current can seem like a somewhat arbitrary measurement just meant to facilitate a...
