Ohmic and Non-Ohmic conductors
Ohmic conductors are conductors that obeys the ohms law while conducting current. In this conductors, current flowing is directly proportional to voltage across the conductor. Most of metal conductors are Ohmic conductors. In simple terms, for an Ohmic conductor, the relationship between voltage and current is linear. Non-Ohmic Conductors: A non-ohmic conductor, on the other…

Need for a break? That is very much in order
We all need a break from anything that keeps us engaging for a long time. Whether good or bad, everything that takes our and time soon causes us feeling of resentment. We therefore longs for a break from anything that is too much for us. The things that causes us to want a break can…

Resistors: detailed analysis 2
Resistors are materials that offers resistance to the flow of an electric current. Resistors are usually categorized into two: Fixed resistors These are resistor whose resistance is almost constant. Resistors are commonly made from mixture of carbon and carrier material where the two are mixed and baked together. The baked mixture is then covered with…

Quadratic Equations 2
Quadratic equations is any equation of the form ax2+bx+c=0 where a is not zero. In other words, quadratic equation is a quadratic expression that is equated to a zero as a value. solving quadratic equations methods of solving quadratic equations includes: solving Quadratic Equations by factorization consider the quadratic equation: x2+3x-54 = 0. we find…

Potential Difference: Powerful Impact on Electrical Systems
The potential difference between to points A and B (Vab) of a conductor is defined as the work done in moving unit charge from point B to A of the conductor. The figure below illustrates the movement of charge in a conductor under the influence of a potential difference. One volt is equal to one…

The ohm’s law
The Ohm’s law summaries about the relation that exists between the voltage across a conductor and the current flowing through it. To explain and describe Ohm’s law, we can take a nichrome wire and make a coil of many turns. Then, we set up the circuit as shown below. The current flowing through the coil…

Rationalizing a denominator: concise easy approach2
Rationalizing a denominator means eliminating any radicals (like square roots) from the denominator of a fraction. To do this, multiply both the numerator and denominator by a value. This value should make the denominator a perfect square or a rational number. Here’s an example: Suppose you have the fraction: To rationalize the denominator, you multiply…

Quadratic expressions and equations: concise Introduction 1
Quadratic expressions are algebraic expressions of the form ax2+bx+c where a, b, and c are constants and a!=0. Constants means real numbers. if a=0, the expression would be linear rather than quadratic. When a graph of a quadratic expression is plotted against x ,is a parabola is formed. If a is greater than 0, the…
