华What are the factors affect resistance? And Past Year (历年考题IGCSE)
(Material, Temperature, Length, Cross sectional area / diameter) (Mandarin)
Hope these video can help students fast revision and prepare IGCSE
What are the factors affect resistance?
1. Material 2. Temperatue 3. Length 4. Cross sectional area / diameter
Let us see the relationship
Resistance is directly proportional to length
Resistance is inversely proportional to cross sectional area
Resistance is inversely proportional to diameter square.
