How measure the value of resister?
To measure the value of a resistor, apply a voltage and measure the voltage across the resistor and the current through the resistor. Use Ohm's law: Resistance equals Voltage divided by Current. Start with a small voltage and increase gradually until a reading is obtained, but be careful that the power dissipation (watts = volts times amperes) of the resistor is not exceeded. Simpler solution: Use an ohmeter.
Why placing the ammeter between the potential divider and the voltmeter will give an incorrect value?
beacause ammeter is use to measure the current not to measure the voltage
How do you measure the current and voltage in high tension line?
To measure high voltage use suitable instrument transformer (potential transformer) Very carefully. It can kill you. The higher the voltage the more the danger or arcing over even when two conductors are not touching. Voltage meters are rated and the rating should not be exceeded. Depending on the voltage you will need the proper meter and a high voltage probe rated for the voltage you are measuring. If you don't know what you are doing, don't mess with high voltage. Leave to the pros.
Why can a semiconductor measure temperature?
Semiconductor resistance depends on temperature. So, you can use a shunt resistor to measure semiconductor voltage with a given current and, then, obtain temperature.
In the unknown of measuring the voltage what should be the setting of VOM selector?
Use the highest available voltage setting. One should know the system voltage before attempting to measure, other wise it may lead to accidents.
How do you get higher voltage from a fruit battery?
use a metals further away from each other on the reactivity series (I think). but using more electrolytes (more fruits i.e. 4 lemons instead of 1 etc) will definitely give a higher voltage. the more fruit, the bigger the voltage. :D
What do you use to measure voltage in an electronic circuit?
A Voltmeter.
What unit do you use do measure voltage?
Believe it or not, THE VOLT.
How do you measure the volts in an orange?
you use a miltimeter and dissimilar metals
What is The Function of Meter?
it is use to measure electric potential (voltage).
How do you use an analog multimeter to measure voltage?
Just set to AC or DC volts and probe the two points you wish to measure voltage across.
What is the function of potentio meter?
it is use to measure electric potential (voltage).
Voltmeter is used for?
A volt meter is use to measure the voltage of the circuit.
How is voltage measured?
Use a voltmeter with a high input impedance and measure at the source the voltage.
What is the use of a volt meters as a laboratory tool?
To measure voltages and voltage drops
How do you measure the peak voltage on a occiloscope?
on most newer oscilloscopes there is a measure button that will allow you to pick peak voltage from the menu. If your o-scope doesn't have this measure button, you will have the use the knob that controls the horizontal cursor and just move it to the top of your wave. The peak voltage is the voltage from the 0 point of the wave to the top of the wave.
