Topics in Current Electricity

1

Electric Potential and Potential Difference

  • Electric potential is like the 'electric level' at a point - similar to height in case of water flow
  • Positive charges flow from higher potential to lower potential
  • Electrons (negative charges) flow from lower potential to higher potential
2

Electric Current

  • Electric current is the flow of electric charge through a conductor
  • Free electrons in metals are the actual charge carriers
  • Conventional current direction is opposite to electron flow direction
3

Resistance and Ohm's Law

  • Resistance is the opposition offered by a conductor to the flow of current
  • Resistance depends on material, length, area of cross-section and temperature
  • Ohm's law relates voltage, current and resistance
4

Conductors and Insulators

  • Conductors have very low resistance and allow current to flow easily
  • Insulators have extremely high resistance and do not allow current flow
  • Metals are good conductors due to presence of free electrons
