# Resistance In A Wire Coursework Evaluation

Switch the meter to its voltage mode, connect it across the specimen’s connection points, and re-connect the battery, quickly noting the voltage indication.You don’t want to leave the battery connected to the specimen for any longer than necessary for obtaining meter measurements, as it will begin to rapidly discharge due to the high circuit current, thus compromising measurement accuracy when the meter is re-configured and the circuit closed once more for the next measurement.In electrical circuits, resistance is the property of an electric conductor by which it opposes a flow of electricity and dissipates electrical energy away from the circuit.

Chromebook compatible sims Windows Systems: Microsoft Edge and Internet Explorer 11, latest version of Firefox, latest version of Google Chrome.A current is passed through the unknown resistance and measured.The voltage dropped across the resistance is measured by the voltmeter, and resistance calculated using Ohm’s Law (R=E/I).When two meters are used, this is not as significant an issue, because the current and voltage indications may be recorded simultaneously.Take the voltage measurement and divide it by the current measurement.Imagine trying to measure the diameter of a cotton thread with a yardstick, or measuring the weight of a coin with a scale built for weighing freight trucks, and you will appreciate the problem at hand.One of the many sources of error in measuring small resistances with an ordinary ohmmeter is the resistance of the ohmmeter’s own test leads.i Pad: i OS 11 Safarii Pad compatible sims Android: Not officially supported.If you are using the HTML5 sims on Android, we recommend using the latest version of Google Chrome.For experimenters on a budget, this may not be possible.Whatever ammeter is used should be capable measuring at least a few amps of current.
