Resistor introduction
Did you know?
WebA resistor is anything that electricity can not travel through easily. When electricity is forced through a resistor, often the energy in the electricity is changed into another form of energy, such as light or heat. The reason a light bulb glows is that electricity is forced through tungsten, which is a resistor. WebTo test the ohmic and non-ohmic behavior in a resistor and a bulb. Ohm’s Law: When the temperature of a metallic conductor is kept constant, the current through the conductor is proportional to the potential difference across it; I α V. This statement is known as Ohm’s law. Materials obeying Ohm’s law thus have a constant resistance at constant temperature.
WebIn a schematic a variable resistor looks like a normal resistor with a line reaching around and pointing back at itself. You may also be wondering why the potentiometer has three legs, when two seems to be enough to work as a variable resistor. We will get to that in a moment, but first, I need to introduce an important concept. WebA resistor limits the electric current that flows through a circuit. Resistance is the restriction of current. In a resistor the energy of the electrons that pass through the resistor are …
