  • Electrical Resistance - Georg Ohm

    Georg Simon Ohm (16 March 1789 -- 6 July 1854) was a German physicist and mathematician. As a high school teacher, Ohm began his research with the new electrochemical cell, invented by Italian scientist Alessandro Volta. Using equipment of his own creation, Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current. This relationship is known as Ohm's law.

  • A Light Bulb Mystery- Electric Resistance // Homemade Science with Bruce Yeany

    A 110 volt light bulb and a 1.5 volt mini light bulb are wired in series to a nine volt battery. What will happen when the electricity flows? This is a nice simple demonstration of how temperature can affect the resistance in a conductor. The result is called a positive temperature coefficient. In metal conductors, there are already a large number of free electrons flowing through it, the vibrations of the atoms cause many collisions between the free electrons and the captive electrons. Each collision uses up some energy from the free electron and is the basic cause of resistance. The more the atoms bump around in the material, the more collisions there are and the friction causes the material to heat up, this then increases the resistance causing the decrease in current flow.

The SI unit of electrical resistance is the ohm , while electrical conductance is measured in siemens . An object of uniform cross section has a resistance proportional to its resistivity and length and inversely proportional to its cross-sectional area. All materials show some resistance, except for superconductors, which have a resistance of zero. The resistance of an object is defined as the ratio of voltage across it to current through it , while the conductance is the inverse: For a wide variety of materials and conditions, "V" and "I" are directly proportional to each other, and therefore "R" and "G" are constant . This proportionality is called Ohm's law, and materials that satisfy it are called "Ohmic" materials. In other cases, such as a diode or battery, "V" and "I" are "not" directly proportional, or in other words the "I–V" curve is not a straight line through the origin, and Ohm's law does not hold. In this case, resistance and conductance are less useful concepts, and more difficult to define. The ratio V/I is sometimes still useful, and is referred to as a "chordal resistance" or "static resistance", as it corresponds to the inverse slope of a chord between the origin and an "I–V" curve. In other situations, the derivative \frac \,\! may be most useful; this is called the "differential resistance". Wiz Science™ is "the" learning channel for children and all ages.

Have any doubts? Follow this link http://avanti.in/peerlearning/signup and ask from the experts. It’s free. Class 10 Physics – Electricity Electricity is everywhere around us. We use so many appliances in our daily lives which are driven by electricity. How a fan starts working when you switch it on, the lights turn on when you switch them on. You all know that this is electricity which is making all this happen. But what is electricity? How it travels in the wires? What is the constituent of this electricity? All these questions will be answered in this chapter. Here, we’ll learn 1. What are charges? 2. What is electric potential and electric current? 3. Ohm’s law experiment. 4. What is ohm’s law and what is a resistance? 5. What is resistivity and how it changes with temperature? 6. Combinations of resistors. 7. What are ammeter and voltmeter and what are their uses in the circuit? 8. Heating effect of current.

What comes to mind when you think of electricity? Current, voltage and resistance. What affects the resistance? What makes a conductor be what it is and for that matter, how is it different from an insulator? What happens when the kinetic energy of electrons is gone? Learn about electricity and resistance in a very interesting way through this module. Electricity can be defined as the movement of charged electrons or the charged protons, dynamically as a current. The charged electrons create charge, which are bind together to do work. The electric bulb, fan and other electronic equipment’s work by binding the electrons. Electricity is measured in units of power called as Watts and it is denoted by the letter W. Current can be defined as the rate at which the charge is flowing. An electric current can be measured using a device called as ammeter and the SI unit for measuring an electric current is the ampere. Voltage can be defined as the difference in charges between the two points. It can be measured by direct current (DC) and alternating current devices. Resistance is the tendency of a material to resist the flow of current. There are several factors that affect the resistance. These includes the material of a wire, thickness of wire, length of a wire and temperature of a wire. The resistance of an electricity is measured in Siemens, which is denoted by the letter S and the S.I unit of resistance is ohms which is denoted by the Greek alphabet symbol Omega - Ω. The resistance of any substance can be calculated by the Laws of Resistance. The main difference conductor and insulator is in conductor electric current flows freely whereas in insulator electric current cannot flows freely.

There's a saying that "it's not the volts that kills you, it's the amps" and while that's true in a way, you can't have amps without volts and skin resistance plays a big part too. This video explores all this, introducing voltage, current and resistance for those new to these things.
