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
