OHMS LAW
Storyboard Text
- Me too
- I think it's from chapter electricity
- Today I'll be teaching Ohm's Law
- OHM's LAW
- It gives the relationship b/w current and potential difference
- Can anybody tell me what is it?
- Do you knowwhat factors affects the electrical resistance?
- I=V/R
- It means that current is directly proportional to potential difference and inversely proportional to resistance.
- Yes, it's absolutely correct. Well done
- Resistance is a property of conductor due to which it resists the flow of electric current through it. Am I right?
- What is resistance
- Yes, absolutely
- Is it not a constant quantity?
- No, I don't think so.
- It depends upon:Length of the conductorArea of cross section of the conductor.
- Yes, it depends on all four factors.
- It also depends upon nature of the material and temperature of conductor.
