How do you draw a circuit diagram of an electric blanket?
The way I have done this with things such as heaters, window defrosters, etc. is to model the heating element as a resistor (or a set of resistors in different parallel and series combinations, based on the layout). The wire used in the electric blanket (the heating elements) should have a specific resistance per length; calculate the length of the different sections, and create a lumped resistive element of this total length.
Is every resistance load resistance?
No. Load resistance is the value of the element actually doing the work of the circuit it is connected to. A speaker connected to an amplifier is the load.
What is the main objection of ohm's law in measuring resistance?
Temperature. Ohms law is applicable to measure resistance of an element at constant temperature only.
Why does the chord of an electric heater not glow while the heating element does?
The element is made of special high resistance wire so the power is dissipated in the element rather than the low resistance cord.Power(watts) = Resistance (ohms) X {Current(amperes)}squared
What is a passive element in a circuit?
A passive element is an element of the electrical circuit that does not create power, like a capacitor, an inductance, a resistor or a memristor.
How does the resistors work in a integrated circuit?
A resistor implements electrical resistance as a circuit element. It works in an integrated circuit by reducing current flow, and to lower voltage levels within circuits.
Why does the cord of an electric heater not glow while the heating element does?
The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.
What is a Memristor?
a memristor is the fourth passive element in the electric circuit joining the resistor,inductor and capacitor , the word memristor is the concatenation of "memory" and "resistance"

How do kettles transfer energy?
They transfer energy by conduction. The element is essentially a huge resistor. When the power is switched on - the resistance of the element causes it to heat up. The heat is transferred to the water - which gets hotter.

What is the working principle of resistors?
A linear resistor is a linear, passive two-terminal electrical component that implements electrical resistance as a circuit element. The current through a resistor is in direct proportion to the voltage across the resistor's terminals. Thus, the ratio of the voltage applied across a resistor's terminals to the intensity of current through the circuit is called resistance. This relation is represented by Ohm's law: Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in most electronic equipment. Practical resistors can be made of various compounds and films, as well as resistance wire (wire made of a high-resistivity alloy, such as nickel-chrome). Resistors are also implemented within integrated circuits, particularly analog devices, and can also be integrated into hybrid and printed circuits. The electrical functionality of a resistor is specified by its resistance: common commercial resistors are manufactured over a range of more than nine orders of magnitude. When specifying that resistance in an electronic design, the required precision of the resistance may require attention to the manufacturing tolerance of the chosen resistor, according to its specific application. The temperature coefficient of the resistance may also be of concern in some precision applications. Practical resistors are also specified as having a maximum power rating which must exceed the anticipated power dissipation of that resistor in a particular circuit: this is mainly of concern in power electronics applications. Resistors with higher power ratings are physically larger and may require heat sinks. In a high-voltage circuit, attention must sometimes be paid to the rated maximum working voltage of the resistor. Practical resistors have a series inductance and a small parallel capacitance; these specifications can be important in high-frequency applications. In a low-noise amplifier or pre-amp, the noise characteristics of a resistor may be an issue. The unwanted inductance, excess noise, and temperature coefficient are mainly dependent on the technology used in manufacturing the resistor. Type your answer here...
What are the factors affecting the electric power industry?
Resistance Resistance is one of the biggest factors affecting power flow in a network. Resistance impedes the flow of electricity. Every element of an electric network has some amount of resistance. The electricity and power of a network will follow the path of least resistance. In order to calculate the power of a resistive element, such as a resistor, at least two of three things need to be known: the resistance of the element, the voltage across the element and/or the current through the element. The power of an element can be calculated either by voltage times current; current squared times resistance; or voltage squared divided by resistance. Load The type of load attached to a network will affect a networks power flow as well. A resistor connected as a load to a network will generate a constant power flow. An electric motor will generate a very high power during startup due to the high current needed to start the motor. As the motor reaches its normal speed, the power needed will drop and stabilize to a fairly constant state. The power needed from the network will remain constant as long as the motor's speed and load are constant. If the motor's load increases, the power needed from the network will increase. Circuit Type There are two basic types of circuits, series and parallel circuits. In a series circuit, all of the current flows through one load. In a parallel circuit, there are multiple paths for the current to supply multiple loads. Each branch gets a fraction of the current depending on the resistance of each branch element. This also means that each branch will use a different amount of power.
Is a resistor bilateral element?
Yes, a resistor has two sides, and furthermore they are interchangeable.
