I can't do all the math for that but if it helps that's a 1,077.3 watt heat discharge.

What is the resistance in a discman if it is connected to an 8.6V battery and draws a current of 0.9 Amperes?
I have no idea
If electric heater works on 115 V and draws 3 A of current how much power does it use?
The formula you are looking for is W = I x E.
A red resistor draws more current than a blue resistor when they are connected to the same battery which resistor has the lower resistance?
The voltage of a battery goes as the current times the resistance (V=IR). Because the voltage is being held constant, the resistor that draws the most current will have the lower resistance.
A resistor has a resistance of 176 ohm How many of these resistors should be connected in parallel so that their combination draws a current of 5 amperes from a 220 volt supply line?
4 resistors were connected in parallel it yields 5A of current from 220V supply.
An electric motor draws a current of 11.5 A in a 240 V circuit What is the power of this motor in W?
11.5 x 240 = 2760W motor.
An electric iron always draws a current of 3.4 amp from the 220v supply line what current will this electric iron draws when connected to 110v supply line?
1.7amp
An electric appliance draws 1.5 amperes of current when it is connected to a 24-volt source - What is the resistance of this appliance?
The formula is Resistance= Voltage/ Amps(current) In your example: R=50/2.5, so the answer is 20 ohms.
What is the resistance in a discman if it is connected to an 8.6V battery and draws a current of 0.9 Amperes?

Does an electric heater use less kwh on lower setting?
Yes. It draws less current.
If electric heater works on 115 V and draws 3 A of current how much power does it use?
The formula you are looking for is W = I x E.
An alarm clock draws 0.5 a of current when connected to a 120 volt circuit calculate its resistance?
240 ohms
How do you measure the size of electrical cable for an electric shower?
Wire is sized by the amount of amperage the device to be connected draws. Without this data the question can not be answered.
A red resistor draws more current than a blue resistor when they are connected to the same battery which resistor has the lower resistance?
The voltage of a battery goes as the current times the resistance (V=IR). Because the voltage is being held constant, the resistor that draws the most current will have the lower resistance.
What is the resistance of an electric frying pan that draws 12 amperes of current when connected to a 120 volt circuit?
Given R=? I=12 ampere V=120 Volts equation I=V divided R Solution; R=12 ampere 120 Volts answer (10)
Why the rotor winding of a synchronous motor is usually connected to an external resistance during start up?
because at start the motor draws larger quantity of current and this may affected the rotor windings in order to limit current always resistance is connected.
