## Where does heat come from in a circuit?

where does the heat energy come from? Energy in a resistive electric circuit is supplied by the EMF , the power source. This becomes kinetic energy of the electrons , which interact in the resistive part of the circuit with the molecules of the solid, the energy becoming vibrational and rotational levels and then heat.

Is heat more in series or parallel?

Heat is generally produced due to resistance.In series combination all the resistors are connected in the same plane in a series so there are my resistances in the path of current.so due to opposition heat produces. in parallel the current is divided into two or more paths so resistance effect is less.

What is the function of a heater in a circuit?

An electric heater is an electrical device that converts an electric current into heat. The heating element inside every electric heater is an electrical resistor, and works on the principle of Joule heating: an electric current passing through a resistor will convert that electrical energy into heat energy.

### How is heat caused in an electrical circuit?

The electrical resistance in the wiring , resist the motion of electrons, the electrons bump into atoms on the outside of the wire, and some of their kinetic energy is given to the atoms as thermal energy. This thermal energy causes the wire to heat up.

Does series circuit overheat easily?

Series circuits do not overheat easily. The current that flows in a series circuit has to flow through every component in the circuit.

How many amps does a heating circuit have to have?

According to the National Electric Code heating circuits are considered a continuous load and therefore must be derated by 25%. (For example: a 20 Amp heating circuit cannot have more than 16 Amps of load connected.)

## Where does the wiring go for a floor heater?

The electrical circuit is installed to the location of the thermostat, and the cables of the floor heat mat are brought to this same junction box. The incoming circuit power will be the same as the Line, and the cable wiring is connected as the Load. Specific instructions will come with the thermostat for the floor heat system that is chosen.

What kind of electrical circuit do I need for a floor heater?

This will also specify what the electrical circuit requirement will be. Many popular floor heating systems are available for 120 volt or 240 volt circuits. I prefer 240 volt circuits because this will help maintain a balanced load of the electrical service which will also help keep the electrical utility cost down.

How is the voltage of a heat sensor circuit set?

Here, the voltage of this circuit can be set by using a potentiometer at the pin-2 of IC. The circuit can be designed to activate or deactivate a device at a specific edge temperature. The temperature can be indicated by using two LEDs namely green LED. The secondary IC o/p enlarges in proportion to the temperature by 10 mV/°.
