Proportionality relation in electric power

Power is directly proportional as well as inversely proportional by two formulae.How does one justify? P=V2/R as well as p=I2 R.   Answer: This means that for a given current, (i.e, when current is kept constant) Power is directly proportional to resistance. eg, when a number of appliances are connected in series, the same current…… Continue reading Proportionality relation in electric power
