An oscilloscope is not an instrument to 'calculate' voltages or currents. It is meant to measure.How to calculate Voltage and current at both side with oscilloscope?
An oscilloscope is not an instrument to 'calculate' voltages or currents. It is meant to measure.
Voltage can be measured directly. Be careful with high voltages. Special high voltage oscilloscope probes or voltage dividers may be necessary.
This can done for DC but in case of AC what to do?Put a (small) resistor in series with the wire where you want to measure the current. Measure voltage across the resistor and determine I=V/R. Again be very careful when it comes to high voltages.
I didn't say you can't. Of course, an oscilloscope is used to display a waveform and to get measurements from this display.Can 't we measure with curve in oscilloscope?
This works for AC, too.This can done for DC but in case of AC what to do?
you will still need to convert the smaller current to a voltage using e.g. a resistor.
Not only undefined, but potentially dangerously high, depending on the specific parameters of the primary circuit and the transformer used.If it doesn't have one, the voltage is undefined
ok, yes it is working in AC i have seen in simulationsThis works for AC, too.
i am familiar with in phase when there is phase difference i cant calculate.
Current can measured only indirectly by an oscilloscope. Put a (small) resistor in series with the wire where you want to measure the current. Measure voltage across the resistor and determine I=V/R. Again be very careful when it comes to high voltages.
Typically domestic customers are billed for real power and large commercial customers for apparent power.
