How do you calculate the energy dissipation by bulbs of different power rates connected in series and in parallel?
For lamps in parallel, it's straightforward, as you only need to add the individual power ratings to find the total power rating and multiply this value for the time over which they operate, to determine the energy dissipation.
For lamps in parallel, it's far more complicated. Lamps in parallel are not subject to their rated voltages and, so, cannot operate at their rated powers. In fact, the lamp with the lowest power rating will actually burn the brightest! Trying to calculate what is going on is further complicated by the fact that there is significant difference in the resistance of a lamp when it is operating at its operating temperature and when it is cold, and you cannot determine these resistances theoretically. So, while you can determine the answer to your question experimentally -by measuring the current and voltage- it is not practical to calculate the answer you are looking for.
What else can I help you with?
What is a resistor bank?
In simple way resistor bank contains number of resistors in series or parallel combination. They are connected in parallel to decrease the resistance and increase current rating and power dissipation.And they are connected in series to increase resistance and power dissipation.
Are devices of home connected in series or in parallel?
Home devices are connected in parallel and not in series.
Voltmeter is connected in parallel with resistor?
A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.
How are series circuits and parallel circuits the same?
They are not. They are connected differently, and the voltages and currents behave in different ways.
How does voltage remains constant in resistors connected in parallel?
It is not necessary for anything about them to be the same.All that is necessary is that they create the desired equivalent resistor, having the correct resistance and power dissipation rating without overstressing either resistor.

How is resistivity connected to resistance?
Resistance is connected in parallel with voltmeter or say, voltmeter is connected in parallel with resistance.
How are voltmeters connected in a circuit: in series or parallel?
Voltmeters are connected in parallel in a circuit.
How can you define power dissipation in a resistor in series or parallel circuit?
Power dissipation in a resistor, or any other type of load, for that matter, is measured in watts and calculated as volts times amperes. It does not matter if the resistor is in a series or a parallel circuit, so long as the volts and amperes in the calculation is for that one resistor. Obviously, volts and amperes is distributed amongst the components of a circuit, and series vs parallel can have a significant affect on that distribution, so you will need to calculate or measure them on a case by case basis.
Are devices of home connected in series or in parallel?
Home devices are connected in parallel and not in series.
Which home appliances are connected in parallel and which in series?
All home appliances are connected in parallel.
What is the equivalent resistance of the parallel circuit you have connected?
In principle, it is infinite. I have not connected a parallel circuit in ages.
Is a voltmeter connected in series or parallel in an electrical circuit?

How do you calculate the equivalent resistance connected together in parallel?
Let the equivalent resistance be R and let there be 3 resistors namely R1,R2 and R3, connected in a parallel way. Now, the relation is: 1/R = 1/R1 + 1/R2 + 1/R3
