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. The number of free electrons depends on the material and more free electrons means a better conductor‚ i.e. it has less resistance. For example‚ gold has more free electrons than

Antibiotic resistance results from bacteria changing in ways that make those antibiotics no longer useful. Resistance is a common yet problematic issue in treating pulmonary exacerbations or infections in people with Cystic Fibrosis (CF). Not all bacteria are bad. However‚ there are some that can cause infections. As bacteria are exposed to antibiotics over time‚ resistance may develop‚ and the number of antibiotics we have to kill the bacteria decreases as well. Thus‚ it is important to learn
