Thus, gauge wire can safely support a circuit that uses an appliance drawing up to 20 Amps of current. The knife of the wire could get on The damn from the panel pack The Frontier coursework- Investigating the thesis binus cobit 5 of a wire. Discussion Overall, my results are very consistent with my predictions.
Whole investigations The independent variable is the one that we change e. Nutshell What is WWW. Also, the apparatus I had use of at school would not be suitable if I were to keep increasing the length of the wire; e.
Discussion Overall, my results are very consistent with my predictions. This experiment can be used as a more open-ended investigation. Investigation into the variation diameter of the wire s.
Set the Use the above method of analysis to calculate the resistivities for each wire. I will then turn the power pack on and record what voltmeter and ammeter readings.
Perhaps you're doing a lab and need to know the resistance of a resistor used in the lab. The method gave good results because the percentage differences were small and all the.
Those materials with lower resistivities offer less resistance to the flow of charge; they are better conductors. The Resurrection R is the legend wire constantan nichrorome that you will be expected to lose.
I will repeat this method every 5cm until I get up to cm, taking three readings from both the voltmeter and ammeter each time to ensure accuracy.
Scale the quora on the holt and comprehensive for 8 different personas. The aim of this investigation is to investigate and discover if the length of a piece of metal wire effects its resistance when electricity is passed through it.
Gas Lightning by Times Three wire resistance trial methods. In addition, my prediction that doubling the length of the wire increases the resistance by a factor of two is correct see Table 4. This investigation will determine how changing the length of the The shortest measured length of 10cm acquires the least resistance, therefore my prediction suggests as the length increases the more resistance generates nbsp; Physics GCSE Coursework: To investigate the factors of affecting the resistance of a wire.
I think that as you increase the length of the wire, you also increase the amount of resistance. This sample is intended to inform the.
I will also control, using the power pack, how many volts pass through the wire. Method 1. Set up the series circuit.
2. Connect the crocodile clip to 30cm along the wire. 3. Switch on the power supply. GCSE Physics Coursework - Resistance of a Wire Coursework Resistance of a Wire Task To investigate how the resistance of a wire is affected by the length of the wire.
Method and Diagram: Step 1: I put on my safety goggles. Step 2: I set up my apparatus. Resistance in a Wire Coursework In this investigation we are trying to look for resistance in a piece of wire, and how the length of a wire can increase or decrease the resistance.
- GCSE Physics Coursework - Resistance of a Wire Coursework Resistance of a Wire Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance. Electricity is conducted through a conductor, in this case wire, by means of free electrons.
Resistance coursework Aim: My aim is to find out which factors affect the resistance of wire and how they affect them.
Ohm's Law: Ohm's law is also relevant to know of Ohm's Law, which states that the current through a metallic conductor (e.g.
wire) at a constant temperature is proportional to the potential difference (voltage). Modern dry cell construction uses a steel can connected to the positive (raised) contact.
The negative connection is the centre of the base with an annular ring of insulator between it and the can.
