Free gcse physics coursework essay resistance in a wire – gcse science – marked by physics (2, 682) religious resistance in a wire i am trying to find out if the filament bulb obeys ohms law resistance of a wire – essay – this essay resistance of a wire and other 64,.
- is a filament bulb an ohmic resistor first of all i did some research because to answer the question 'is a filament bulb an ohmic resistor' i needed to know what an ohmic resistor was ohm's law the current flowing through a metallic conductor is proportional to the potential difference. A filament lamp does not obey ohm's law because, for tungsten, the ratio of voltage to current isn't a constant for changes in voltage metals such as tungsten are, therefore, termed 'non-linear' or 'non-ohmic' there seems to be a major misconception surrounding ohm's law. The values of voltage and current and verify ohm's law sample lab-report on verfication of ohms law 25 ohm's law circuit reporting an incident of bullying ohm's law is an empirical formula which relates the voltage drop across a resistor 18 mar 2010 - 3 min - uploaded by msbarnetta brief demonstration of how to set up a lab for ohm's law.
It still obeys ohm's law, however, as the relationship that ohm's law describes still holds in other words, as the resistance increases, the current will decrease, just as ohm's law says it will. Does a light bulb obey ohms law essay a+ pages:3 words:649 this is just a sample we even could carry the experiment on until the filament melts, and see how much voltage it can take also, we could add a lamp or two into the circuit and see if this affects the resistance in any way does a light bulb obey ohms law specifically for.
I think this was caused by air already in the tube being pushed out to overcome this i could have measured how much o2 started in the tube and then subtracted that from my 1st measurement. A filament lamp does not obey ohm's law because, for tungsten, the ratio of voltage to current isn't a constant for changes in voltage metals such as tungsten are, therefore, termed 'non-linear.
A light bulb is non-ohmic because it does not obey ohm’s law according to ohm's law, the ratio of potential difference to the current flowing through a conductor is constant, providing all other influences such as temperature are kept constant when a material is ohmic, the resistance remains.

Introduction: in the following experiment, i predict that the filament bulb in which we are testing, on will not obey ohm’s law their are many factors which make me believe this, such as the temperature of the bulb. Filament bulb obey ohms law 1,534 words, approx 6 pages my aim is to find out whether or not a filament bulb will obey ohm's law making it an ohmic conductor this is where the resistance is constant and the same.
