Temperature Dependence of Resistance

Science > Physics > Current Electricity > Temperature Dependence of Resistance In this article, we shall study the effect of temperature on the value of resistance and thermistors and their uses. A metallic conductor consists of a large number of free electrons. These electrons are always in a state of random motion. When a potential […]

Introduction to Current Electricity

Science > Physics > Current Electricity > Introduction In this article, we shall study the concept of current electricity, the resistance, ohm’s law, and the conductance of a conductor. Electric Current Through Conductor: A conductor is made up of very minute particles called atoms. Atoms consist of a positively charged nucleus and negatively charged electrons […]
