A voltmeter would measure the voltage. If you measure the voltage drop over a known low resistance you get a kinda-sorta idea of the power available.

How much voltage does it take to power a clock?
My big kitchen clock runs on a single AAA cell. That's 1.5 volts. My son has a solar-powered watch. The solar cell is a lot less than 1.5 volts. I used to have a clock in my office that ran on the voltage between two needles stuck into a potato. I had to get rid of it after a long weekend when the clock was stopped and the office was full of fruit flies. But the potato was not a tremendous voltage source. I don't know what's the smallest voltage that a clock has ever run on, but it's obviously a lot less than one volt.
What is power factor of resistor?
A resistor doesn't have a power factor. However, if a circuit is pure resistance in nature the power factor will be one when a voltage is applied and a current flows in the circuit. The power factor is a measure of the relative phases of the current and voltage in a circuit.
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.
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.
What is 5280W to Kilovolt Ampere?
1000v times 5.2amps.AnswerThe watt is used to measure true power. The volt ampere is used to measure apparent power. So, you cannot convert one to the other, as they measure different quantities. However, when the current and voltage are in phase with each other (i.e. having unity power factor), the apparent power will equal the true power.
How does a potato clock work?
A potato can power a clock because all fruits and vegetables have an electric current in them, so the potato's act like a battery and supply the clock with electricity.
Does a potato produce enough volts to power a clock?
yes
How long can a banana power a clock?
a banana can power a clock for a pretty long time, just like a potato can control the universe
How many potato batteries does it take to power an alarm clock?
2
Can you put zinc and copper wires from a two potato clock together to power a clock with one fruit?
Yes you can
Why is a potato clock a science fair project?
A potato clock is a science fair project because it uses a electricity to power the clock. One of the things in sciencce is finding how the electricity and the potato chemicals stuff, things powers the clock. It gets pretty complicated. Theres TONS of reasons how its a science project.

Can you make a battery out of a potato?
Yes , below at the related link you will find instructions - you can even power a clock .
do they still sell those potato clocks?
Star Magic manufactures a clock which is run on the power of potatoes.
Writing a report on a potato clock?
The graph that can be used to best describe a potato clock is a line graph. It will have the two values: the time the potato is cooked and the water temperature. The points can be plotted and connected to show their relations.
Is Decibel is the unit of power ratio?
It can be the power ratio. If you measure voltage or sound pressure it is not the power ratio.
Is the problem the title to your science fair project?
Usually. But it doesn't have to be. For example, one of my previous science fair project's title was 'POTATO POWER' and it was about how to make a potato clock.
