Study Notes
Resistor Color Coding
- The color bands on the body of a resistor indicate the resistance value.
- The last band on both 5-band and 4-band resistors indicates the tolerance value.
Determining Resistance Value
- The resistance value of a resistor is determined by decoding the color bands.
- Another way to determine the resistance value is by using a resistor value chart.
Resistance and Tolerance
- Rmax represents the maximum resistance value, calculated by Rmax = R + (R * T), where T is the tolerance value.
- The tolerance value can be found in the resistor tolerance chart.
Ohm's Law
- Ohm's Law states that V (voltage) is equal to I (current) multiplied by R (resistance), or V = IR.
- R (resistance) is expressed in ohms when V is in volts and I is in amperes.
- The symbol for electrical resistance in electrical diagrams is R (omega).
Conductors and Insulators
- Copper offers little resistance to the passage of current, making it a good conductor.
- Insulators are materials that resist the flow of electric current.
Ohm's Investigation and Contributions
- Ohm's investigation into electrical resistance led to the development of Ohm's Law.
- The unit of electrical resistance, the ohm, is named after Georg Simon Ohm.
Other Key Facts
- In Fig.(2), 'R' denotes the resistor.
- The aim of the Ohm's Law experiment is to verify the relationship between voltage, current, and resistance.
