Ib: Physics 5.2 'link'

A current of 0.50 A flows through a 20 Ω resistor for 5 minutes. How much heat is produced?

Since energy ((E)) is power multiplied by time, the electrical work converted into heat over time (t) is (E = IVt). Ib Physics 5.2

A top-scoring IB student sees connections. 5.2 does not exist in a vacuum: A current of 0

For a standard wire, resistance depends on its physical dimensions and material properties: Proportional ( Cross-sectional Area ( ): Inversely proportional ( Resistivity ( ): A property of the material itself. The combined formula is: 2. Ohm’s Law and I-V Characteristics A common pitfall for IB students is assuming is Ohm’s Law. It isn't. is simply the definition of resistance. Ib Physics 5.2
