change your resistance, its a little button, or if you are using an older oscilloscope, its a knob that will lower the sensitivity of the display. if it is something way higher than the oscilloscope can measure, you may have to run a resistor or transformer in the line.

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 is the use of the oscilloscope?
If you use a voltmeter to observe a voltage, it can only respond slowly, so if you want to observe a voltage that changes in fractions of a microsecond, you need a voltmeter that can respond at such speeds. It is called an oscilloscope.
How do you measure amplitude of a ripple?
Most true RMS voltmeters can measure the value of a ripple voltage on top of a DC supply, when you place it in AC mode. You can also place a small capacitor in series with a DC voltmeter and that would measure the ripple. The real way to do this, because ripple voltage is not sinusoidal, is to use an oscilloscope, particularly if you want the peak values.
What is the purpose of the voltage divider control in oscilloscope?
This control reduces the amplitude of the applied signal to a point where the whole signal can be displayed on the oscilloscope screen. The amount of voltage reduction is marked on this control switch so that it can be used as a voltmeter.
If the cathode voltage of a forward biased silicon diode is 4.5 v what is the anode voltage?
The nominal forward bias voltage of a silicon diode is 0.7V, depending on current and temperature. If the cathode is 4.5V, the anode should be around 5.2V.

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.
How do you measure peak voltage using oscilloscope?
You measure the peak to peak voltage and divide by 2.
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 rays can be produce by cathode ray oscilloscope?
A: xray emits from TV, OSCILLOSCOPE and some more instruments due to requirement of hi voltage to see the display
How do you set the input voltage of cathode ray oscilloscope?
first we connect the oscilloscope with the function generator or whatever the source of the input voltage , there will be a wave ,we try to adjust its amplitude using oscilloscope ..and this amplitude will be the peak to peak voltage..putting into consideration how volt/ div while measuring the amplitude
How does the anode voltage applied to the cathode ray oscilloscope affects the sensitivity of the CRO?
The anode voltage does not affect the sensitivity of a CRO. The input amplifier and deflection circuit have a greater influence. The Anode voltage will affect the focus and visibility of the trace, in this respect it will affect how you see the result.
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.
What does oscilloscope an measure?
An oscilloscope takes an electrical input signal and converts it into a visible trace on a screen - i.e. it converts electricity into light. An oscilloscope helps us to measure the voltage(maximum)....We can also find frequency from it by using a Equation.. We can use the maximum voltage in this equation i=v(maximum)sinѠt to find 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.
