Is the power in series and parallel different for other appliances like when we connect bulbs in series we take it inversely proportional to resistance but for others we take it directly proportional?

Open in App

Solution

For a single device,the power in both series and parallel is same.
But for a number of devices,the power delivered is different in series and parallel.
But the total power in series and parallel is same.

In series circuit,the formula for power is ,p=i²R.
Here power is directly proportional to R.
We took i here because current is constant in series.

In parallel circuit,the formula for power is,p=V²/R
Here power is inversely proportional to R.
We took V here because,voltage is constant in parallel circuit.

In a series combination of electrical appliances, connected to a constant voltage power supply, if we add one more appliance with resistance R in series, then the total electrical power consumed in the circuit will__.

Q. Assertion :A

60 W

bulb is connected in series with a room heater and combination is connected across the mains. If the

60 W

is replaced by a

100 W

bulb, the heat produced by the heater will be more. BECAUSE Reason: The heat produced in inversely proportional to resistance when the resistances are connected in series across the mains.
