The transfer function is obtained by dividing the sum of the geometric distances on the s-plane from each zero to the point s by the sum of the geometric distances from each pole to the point. How to Find Magnitude…
If you have a two-wire motor, you first need to determine which wire is positive and which is ground. This is a common mistake made by people who want their squirrel cages to look good. In practice, single wire motors…
You can bypass a voltage regulator with the help of an alternate regulator and connect it to the battery. You will also need the plug harness and the wires to connect the regulator to the battery. An alternator turns mechanical…
One of the most difficult techniques to learn is oscilloscope calibration. Getting things perfect might take a lot of time and work. However, if you follow some instructions, you will be able to calibrate your scope more quickly and successfully….
The bleeder resistor size is defined by the formula, R = -t/C*ln(Vt/Vu), where Vt is the momentary voltage, Vu is the initial voltage, C is the capacitance and t is the momentary period. A bleeder resistor is connected in parallel…
The Digital-to-Analog Converter (DAC) and the Analog-to-Digital Converter (ADC) circuits are discussed here. A Digital to analog converter (DAC) converts binary digital data to an analog form by using an R-2R ladder (binary weighted resistor) network and a summing amplifier….
Oscilloscopes are an important tool in any electrical engineer’s lab. A specific and exact guideline is maintained to connect an oscilloscope to a circuit. In particular, proper grounding is very vital for your safety as well as the safety of…
Adjust the vertical sensitivity of the oscilloscope while the waveform is displayed on the screen to get the figure as inclusive as possible without losing any from the top or bottom. Count the number of horizontal graticules on the screen…
You can measure current with an oscilloscope using one of the following methods: Measuring current with a digital multimeter is common. But measuring current that changes over time necessitates the use of an oscilloscope. Most oscilloscopes only detect voltage directly,…
