Investigating the resistance of a wire essay

Further, none of the above should be taken as a legal advice as it is merely my understanding based on a conversation with officers from the Queensland Weapons Licensing Branch. There are lots of things that would make a great EEI.

He eliminated radiation as a possibility as it was so small.

Physics Essay Examples

You could then consider changing the starting pressure or the volume of water or whatever you like. The mere existence of an equilibrium temperature Teq above room temperature is related to the existence of a flow. For large-scale solar plants to maintain their maximum efficiency, the photovoltaic cells must be kept clean, which can be a challenging task in dusty environments.

In the next step is to assist the surgeon in detecting significant differences among our multilingual, multicultural and inter pluriculturality as related concepts. Temperature along a heated metal rod You are well aware that the closer you are to something hot, the higher the temperature.

It is really hard to measure "h" so leave that alone for a while. Nayana pictured and Amanda found that photographing hydraulic jumps was the way to go. Food dye was used to make it easier to see and we used a tray to catch the overflow for later reuse. You will need to work out how to do this.

A big thank you to my grand-daughter for the use of her Play Doh. A Garmin GPS as used in say cycling works best when you're moving, otherwise it meanders around all over the place.

You know that someone will knock it and break one though. To ensure safety in the laboratory whilst the investigation is carried out, laboratory coats and eye protection will be worn at all times and any skin that comes into contact with the chemical will be washed thoroughly.

Below is the plot of such an experiment done by my hero Prof.

Investigating the Resistance of Wire

Measure the capacitance of a home-made capacitor using a digital multimeter with capacitative measurement and vary the number of sheets of dielectric. Resistivity is the longitudinal electrical resistance of a uniform rod of unit length and unit cross-sectional area or simply "how much resistance is in this wire?

What are the sources of error? The final term is Resistance which is the opposing flow of an electrical current. Robert said that he was looking at less powerfulengines in The momentum of the projectile is transferred to the stationery target.

Robins' original work used a heavy iron pendulum, faced with wood, to catch the bullet. The experimental and theoretical graphs.

If a projectile from your trebuchet goes off course and hits someone on the head m away and causes bodily harm then you or the school may be a big legal and medical problem; but it would appear that the police would not consider it an offence under the Weapons Act as it is not a "weapon" and a "behavioural offence" was not intended despite bodily harm being done.

But you can't do this today in class as it is too dangerous.

Lessons In Electric Circuits -- Volume I

The nichrome wire is covered with masking tape so it can't short circuit. Record the results and place in a table. On the left is the bar heater with the Digitec yellow thermometer next to it.

But as Mohamed said " Single bottle In the lab at Moreton Bay College.

Physics - Electricity in the Home Essay

You have to make the flow rate is the same each time. Lots on the internet about this. I don't have the actual voltage outputs vs temperatures, but comparing my best clear day since installation, Pratiques,la litt racie, reflecting on their own courses.

I think that the range of my results was sufficient enough for me to draw a valid conclusion about how the length of the wire affected the resistance.

I used glass so you could see inside but something like a thick piece of wood maybe better. Then with constant illumination, you could put the PV panel on top of a hotplate and crank up the temperature.

When the stopper is removed the water jets out under gas pressure. Video data collection and analysis. I will then turn the power pack on and record what voltmeter and ammeter readings.

Even if your device is not a weapon under the Act your teacher may consider it too dangerous for a school activity.

Resistance of a Wire Investigation

Your Arduino can do this beautifully but so can any of the dataloggers.The longer the nichrome wire is, the larger the resistance will be. This was certainly the case here as the resistance for the 1 metre wire was more than double that of the 0. 5 metre wire.

This larger resistance would be due to the cross-sectional area of the wires. The wire PQ has the resistance of 5 ohms and the driver cell has an emf of V. What is the value of the resistance R if a balance point is obtained at m along PQ when measuring an emf of mV?

Resistance of a Wire Essay that affect the resistance ´╗┐Investigating the Resistance Of A Wire A simple investigation of the factors affecting the resistance of a wire.

For each student group Cells, V, with holders, 2 Crocodile clips, 2 Ammeter (0. Investigating Resistance of a Wire Essay examples - Investigating Resistance of a Wire INTRODUCTION This investigation is about find the resistance of a wire.

Resistance is the slow-down of the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit.
