You can measure current with an oscilloscope using one of the following methods: Measuring the voltage dropped across a shunt resistor.Measuring current with a current probe. 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, not … [Read more...] about How to Measure Current With an Oscilloscope
Electrolytic Capacitor ESR Chart
Low ESR capacitors have lower power losses and internal heating issues than high ESR capacitors. High ESR values shorten the life of an aluminum electrolytic capacitor and reduce performance. Furthermore, a low ESR value enables increased ripple current capacity. ESR(Equivalent Series Resistance), also known as internal resistance, is a number that represents the loss … [Read more...] about Electrolytic Capacitor ESR Chart
How to Zoom In Oscilloscope
To zoom in or out a signal in an oscilloscope, you need to change the scales of the axes. Use the knob for the horizontal axis and set the µs/div to a lower value. This will allow you to zoom on your signal horizontally. To zoom vertically, set the volts/div of your oscilloscope to a lower value. Zooming in on waveforms allows you to view a detail of the signal … [Read more...] about How to Zoom In Oscilloscope
Is Urine Conductive
Urine isn't an ideal conductor of electricity, but it can carry enough to be harmful. It contains salts and other minerals that conduct electricity, and its high water content allows it to easily carry a current. However, the human body is a poor conductor of electricity. Thus the amount of current that can pass through urine is restricted. Because urine contains several … [Read more...] about Is Urine Conductive
How to Test an Oscilloscope
For calibrating a 10:1 probe, the majority of scopes provide a test output. Typically, a 1 kHz, 1 V, or 5 V square wave is used. The first stage is to display the square wave with about three periods accurately. Once you have that, you may horizontally zoom in by setting the timebase to smaller values. To view the slope on the screen, you might need to change the … [Read more...] about How to Test an Oscilloscope
