Hi all, I am doing my physics lab write up. We used a Behr Free-Fall Apparatus to find g. The apparatus "zaped" a piece of paper ever 1/60 of second. What is the Amp of current running through the machine. thanks a ton.

What does it matter? You aren't interested in the composition of the metal in the stand either. Part of physics is knowing what is relevant and what is not - so if you are worrying about the current required to make the spark your teacher might infer that you are missing the point of the experiment. All you are interested in is the frequency of the spark and the distances between the spark burn marks on the tape.bjon-07 said:Hi all, I am doing my physics lab write up.

The spark rate is not necessarily the same as the frequency of the alternating current. The spark is presumably caused by an induction coil with a switch making and breaking contact 60 times/second (like the ignition system on a car). Check the specification for the equipment to find out the number of sparks per second (to verify that it is 60).bjon-07 said:Sorry for the confusion but why I want to find is clylic rate at which the electricity is alternating. This in theory should well tell me how many times per second the deviced will zap the target. I know its not nessarcy to find g, but I would like to be very througll in my lab reprt.
Frequency refers to the number of cycles or oscillations of a wave per unit of time. Amplitude refers to the maximum displacement of a wave from its equilibrium position.
The frequency of a wave can be calculated by dividing the speed of the wave by its wavelength. The amplitude of a wave can be measured by finding the distance between the equilibrium position and the highest point of the wave.
The frequency and wavelength of a wave are inversely proportional. This means that as the frequency increases, the wavelength decreases, and vice versa.
Frequency is a physical characteristic of a sound wave, while pitch is a perception of how high or low a sound is. As the frequency of a sound wave increases, the pitch will also increase.
Frequency and amplitude are key components in understanding and analyzing waves, which are present in many natural phenomena and technological applications. Having a grasp of these concepts can help scientists better understand and predict the behavior of various systems.
