A ohm light and a 150 ohm heater are connected in parallel to a 150 volt power source. what is the total resistance of the lamp and the heater?
50 ohms...!
What current is taken by a heater with a resistance of 24 ohms when connected to 120 volt supply?
I don’t know
How could you find the purpose of a parallel circuit?
For an electrical load, such as a lamp, heater or motor, to operate at its rated power, it must be subject to its rated voltage which always corresponds to the supply voltage. For this to happen, individual loads must be connected in parallel with the supply and with each other. So all the electrical loads in your home, in your car, etc., are ALL connected in parallel.
A 75 ohm light and a 150 ohm heater are connected in parallel to a 150 volt power source. What is the current through the 75 ohm lamp?
2 amps

50 ohms...!
Do all the other lights go out when you turn off an electric light bulb in our home?
No, because devices (light bulb, heater, TV set, and so on...) in our home are connected in parallel.
Does an electric motor have different resistance than an electric heater?
Yes it would be unlikely an electric motor coincidentally exactly matched the resistance of an electric heater.
Where is the heater resistor on a 2003 Chevy Cavalier?
There are heater-resistance wires in the glass of the back windshield.
Are electric heaters connected in series or parallel?
Some are series, some parallel, some both. Depends on the design. Series heaters will have all the heaters fail or shut off should one burn out or open circuit. Should a series heater short out the other heaters will see increased voltage so must be able to handle full voltage or they will overheat and fail. Parallel heaters will not notice if one of the others open circuit. If protection devices, such as fuses or overloads or overtemp, are installed for each heater all others will continue to operate if one shorts out or fails. Parallel heater designs are more common.
What is the voltage of a small electric heater if the heater is drawing 12 amperes and has a resistance of 10 ohms?
Voltage is current times resistance, 1.2 x 110 = 132 volts.
How is resistance used in a space heater?
In an electrical space heater, electrical current dissipates energy into heat, and the heat radiates from the element. In a fuel powered space heater, an orifice throttles the fuel feed (resistance to flow), which controls the heating rate. In a steam powered space heater, an orifice throttles the steam (resistance to flow), which controls the heating rate.
Does the resistance of heater coil remains same when current flows through it?
Typically resistance rises with temperature.
