# Why doesn't using more appliances at home decrease the electricity bill? [closed]

I know that at home the electric circuits are parallel, and this explains why if one appliance (eg bulb) fails, everything else continues to work, but if more devices are added in parallel to each other, their combined resistance should decrease, and thus the total power supplied by them should increase, as $$\mathrm{Power} = V^2/ R$$. It doesn't look like that's the case, what am I getting wrong?

• Appliances don't 'supply' power (your wallet does that). – amI Sep 29 '18 at 16:18
• Perhaps your problem is a linguistic one. You seem to be confusing the physics definition of power with the everyday English one used in e.g. "power company". If you think of your appliances as consuming energy rather than power, the question might answer itself. – jamesqf Sep 29 '18 at 17:11

The power will increase .See the formula given carefully $$V^2/R$$. For constant voltage power is inversly propotional to resistance.As we add one more resistance in parallel overall resistance decreases and hence power increases.Or you can also think in the way if overall resistance decreases then current increases and hence $$P=VI$$ increases
