Can you measure current with an oscilloscope?
Oscilloscopes only measure voltage over time. Current cannot be measured with an Oscilloscope directly, but can be measured indirectly. Measure the voltage across a known load and calculate the current.
Is the amount of space charge created at the cathode is primarily controlled by the tube current?
The cathode space charge is determined by the voltage on the filament.
What is the direction of current flow in a diode valve?
Inside the diode valve the conventional curret flow is from anode to cathode. The electron flow is from cathode to anode.
What is the maximum absolute value reached by a voltage or current waveform?
define the maximum value of an ac wave form
When a 10mA forward bias current and the voltages at the anode and cathode of a diode in a circuit are found to be the same what is the diode most likely to be?
With a 10mA forward bias current, if the voltages at the anode and cathode of a diode in a circuit are found to be the same, then the diode most likely to be shorted.
How can you measure ac?
you can measure ac using a cathode ray oscilloscope. it will project a sinusodial waveform, showing that the current is in the positive direction in the first half and the opposite direction in the second half
How a Cathode Ray Oscilloscope is used to measure Alternating current?
An oscilloscope is, essentially, a voltmeter -it measures current by measuring the voltage drop caused by that current across a standard resistance.
Why current cannot be measured directly using an oscilloscope?
A standard oscilloscope is designed to measure voltage, you need a current probe for your oscilloscope to measure current.
What does the term oscilloscope mean?
The meaning of the word oscilloscope is a device used for viewing oscillations, electrical current or voltage or, with a display on the screen of a cathode-ray tube.
How is an oscilloscope different form a compressional wave?
An oscilloscope is a device that views electrical current or other oscillations on a cathode ray tube screen. A compression wave, meanwhile, is a type of wave that forms rarefaction when it moves down a channel.
Can you measure current with an oscilloscope?
Oscilloscopes only measure voltage over time. Current cannot be measured with an Oscilloscope directly, but can be measured indirectly. Measure the voltage across a known load and calculate the current.
Using a cathode ray oscilloscope how do you measure the current in an electric circuit?
Cathode ray oscilloscope(CRO) is a device used to see the voltage across a particular element of your circuit and the wave form can also be seen on CRO. But you actually cannot measure the current using CRO as it is meant to give the voltage levels across any element in eletrically enegized circuit. however Digital Multimeter can do this job. But while using DMM to measure current one thing should be kept in mind that your circuit should be linear so that if you break the circuit to find current in series the current could not change in circuit.
1 If the voltage applied across a capacitance is triangular in waveform then the waveform of the current is?
rectangular
What does an oscilloscope display?
See the link below for some oscilloscope waveform shapes.
What is a good tester to check ripple current?
An analog oscilloscope.
Why gate is closer to cathode in scr?
A: To partially eliminate the problems with cathode current hugging
What is maximum current?
If you are referring to an a.c. current, then the maximum current is the amplitude of its waveform. For a sinusoidal waveform, the amplitude of an a.c. current is its root-mean-square value, divided by 0.707. For example, an a.c current with an rms value of, say, 10 A will have an amplitude of 14.14 A,
