Why it is impractical to connect an electric light bulb and an electric heater in series?

It would not work because when two things are in series the same current has to pass through both.
Normally an electric light takes much less current than an electric heater and therefore the light has more resistance. Most of the voltage would appear across the light bulb, so you would have a slightly dimmed bulb and a heater giving out very little heat.
It would work if both devices were identical.
Electricity supplies use a constant voltage, e.g. 120 v or 240 v, and all applicances are connected in parallel across the supply.

Why it is impracticable to connect an electric bulb an electric heater in series?
It is impracticable to connect an electric bulb and an electric heater in series because it will divide the voltage.
How do you change a heater from 120 volts 3a to 240 volts 1.5 a?
the simplest solution is by connecting two 120v 3amps heater in series , the same can be used directly on 240v. However the current drawn will still be 3 amps & Not 1.5 amps. The heater output power will be double that of a single heater running on 120v. ( or equvalent to two heaters operating on 120v. supply ) A more expensive method is to use a stepdown transformer which can be powered on 240v & connect the heater on the transformer 120v side. this method will consume approx. 1.5 amps from the 240v supply.
Does an electric fan work by using a series circuit?
If there is only one fan in the circuit then it is in a series circuit. If there is more that one fan then they will be connected in a parallel configuration.
What breaker can I use if I dont have a westinghouse breaker?
The Cutler Hammer BR series will fit and also the Connecticut Electric UBITBC series will fit your Westinghouse service panel.

Can you connect two 24v batteries to get 48v on a kids electric car?
Yes, connect them in series.
Why it is impracticable to connect an electric bulb an electric heater in series?
It is impracticable to connect an electric bulb and an electric heater in series because it will divide the voltage.
Can two electric resistors connect in both series and parallel?
yes two resistors can connect both in series and parallel because when you connect two resistors in a closed loop, the same intensity of current flows across them and also they are connected to the same nodes which are the conditions for series and parallel connections respectively.
Why it is often not practical to connect the electric components (example of lights) in series?
In a series circuit, if one of the light's filiments opens the bulb will go out, but along with that light every other device in the same circuit will stop operating.Think of an electric light circuit, in your home, that is controlled by a switch. When the switch is turned off the light goes out. This is an example of a series circuit where ithe switch is in series with the lamp.
Where can I find a 36v10ah battery for an electric?
If you can't get it from your device manufacturer, you can find (3) 12v 10ah batteries simply and connect them in series to provide your 36v 10ah replacement.
How do you connect a ammeter into a circuit?
connect ammeter in series with load.
How do you connect resistance is series?
I'm going to take this as "How do you connect resistors is series?" just connect one wire of the first resistor to one wire of the second.
How do you wire start and run capacitors into an electric motor?
Connect your start capacitor in series with the start winding.Connect the run capacitor in the common terminal and Line 1 of the power supply.

How do you connect six 6-volt cart batteries?
Connect them in series.
Where is the Engine block heater located on Saturn sl2?
There is no block heater on the s-series That is not right there was an option on the s series but like i said it was an option so.
To construct a battery with a current of 6 amps you would connect six 1 amps cells?
You would connect them in parallel to increase the amerage. If you connect them in series it would increase the voltage. Connected in series-parallel would increase both voltage and amerage.
