No. The heating effect is the product of the square of the current and resistance, where the current is a root-mean-square value.A.C. current is always expressed as a root-mean-square (r.m.s.) value, which is equivalent to a d.c. current which produces exactly the same heating effect. Root-mean-square values are affected by the shape of a waveform, but not by its frequency.
this is called convection current
The process of Convection / subduction current
The most efficient is a geo-thermal heat pump, if properly installed.
Heating is caused by current flow. Certain types of wire like tungsten emit more heat than other types. Lower resistance means higher current for a fixed voltage per Ohm's Law. So the efficiency of heating with electricity depends on the material of the conductor, the operating voltage and the resulting current. In most instances this will be a low resistance with high conductivity.
One uses the thermostat to ADJUST the temprature of your central heating. you should adjust your head and make sure its on properly
how would you show the heating effect of a current?
When the electrode has been properly placed, a radiofrequency current is passed through it, heating the tumor and killing the cancer cells.
how dose alternating current and direct current affect heating, ventilation, and air conditioning
The heating effect of electric current was discovered by James Prescott Joule in the mid-19th century. Joule's experiments showed that the temperature of a conductor increases when an electric current passes through it.
The current supplied to the filament of an electron tube for heating.
Your oven may not be heating properly due to a faulty heating element, a malfunctioning thermostat, or a problem with the oven's power supply. It is recommended to check these components and consult a professional if needed for further diagnosis and repair.

Inspecting and properly maintaining heating systems, chimneys, and appliances; inspecting and properly maintaining heating systems, chimneys, and appliances.
When the direction of current is reversed, the heating effect remains the same. The amount of heat generated is determined by the magnitude of the current and the resistance in the circuit, independent of the direction of the current flow.
Your Thermador oven may not be heating up properly due to issues with the heating element, temperature sensor, or control panel. It is recommended to check these components and consult a professional technician for further diagnosis and repair.
Your Whirlpool Duet dryer may not be heating up properly due to a faulty heating element, a malfunctioning thermostat, a clogged vent, or a broken thermal fuse. It is recommended to check these components and replace any that are not functioning correctly to restore proper heating.
