Electromagnetism

5.2 Develop qualitative and quantitative understandings of current, voltage, resistance, and the connections among them (Ohm’s law).

5.5 Explain how electric current is a flow of charge caused by a potential difference (voltage), and how power is equal to current multiplied by voltage.

Power = Current x Voltage

Resistance= Voltage/Current
Principle-2
