Please explain the concept of Power.
When do we use V2/R and I2R.
Consider this problem:
4 resistors (bulbs) are connected in series and then in parallel. What is the ratio of the heat produced in series and in parallel?
The answer has used V2/R i.e. power is inversely proportional to resistance.
Why cant i use I2R, since the current through the resistors is the same in series?
Please explain.
