The resistance of a light bulb is inversely proportional to its temperature, i.e. a cold bulb has less resistance than a hot bulb. As a result, if you connect three bulbs in series to the same voltage used for one, they will each receive one third of the original voltage, causing them to use less power, causing them to generate less heat, causing them to have less resistance. If you measure the current in the circuit, there will be slightly more than one third of the original current. Given the same voltage, that means that each bulb has less resistance than originally measured, as expected. This characteristic of light bulbs is why they tend to blow out at turn-on. The starting current and power is higher than in the steady state case. You can make a bulb last much longer if you provide a soft start circuit that ramps up the voltage over a short period of time.

What is the meaning of Ohms?
Resistance is the measure of the degree to which an object will oppose an electric current. The SI unit for resistance is Ohm (Ω). Resistance can be found using the formula R=V/I where R=resistance (Ohms) V=the potential difference across the object (Volts) I=the current through the object (Amperes)
What is resistance?
Resistance is the opposition to flow or movement.Resistance in a a mechanical system could be friction, wind, gravity.Resistance can be opposition to a policy, or to an invasion (e.g. French Resistance).Resistance in an electrical circuit is the limiting or opposition to current flow. It is measured in Ohms.----Electrical ResistanceThe technical definition is "Electrical resistance is a ratio of the degree to which an object opposes an electric current through it, measured in ohms."In simplfied terms, electrical resistance is broadly equivalent to friction in a mechanical system. If you applied a voltage to a circuit with zero resistance then you would get an infinite current. In reality all circuits have some resistance which limits the current.We can predict the current in a given circuit using Ohms law:V = I x RWhere:V is Voltage (measured in Volts)I is current (measured in Amps)R is resistance (measured in Ohms)You will often see this in the form E = I x R. It is exactly the same thing, just a different convention where "E" is used for voltage instead of "V"Ohms law is:V=I/RV=Voltage (volts)I=Current (amps)R=Resistance (Ohms)Resistance in an AC circuit is called Impedance (Z)Electrical resistance is the amount that an object opposes electrical current. All things being equal (temperature, purity, etc.), resistance is a function of both its physical geometry and the resistivity of the material it is made from. Impurities in materials and fluctuation of temperature can effect the amount of resistance a material will exhibit.----------Electrical resistance is the amount that an object opposes electrical current.

What is a strain gauge used for and how does it work in measuring mechanical strain?
A strain gauge is a device used to measure mechanical strain, which is the deformation of an object under stress. It works by changing its electrical resistance in response to the strain applied to the object it is attached to. This change in resistance is then converted into a measurable electrical signal that can be used to determine the amount of strain the object is experiencing.
What is the is the measure of an object's resistance to a change in its rotational motion about an axis called?
The measure of an object's resistance to a change in its rotational motion about an axis is called inertia. It is similar to an object's resistance to a change in its linear motion, but it specifically refers to rotational motion. The greater an object's inertia, the more difficult it is to change its rotational motion.
What is the Resistance in change of motion?
Resistance in change of motion refers to the force that opposes the movement of an object. This resistance can come from factors such as friction, air resistance, or the inertia of an object. It acts in the opposite direction of the applied force, making it harder for the object to accelerate or decelerate.

What is a strain gage used for?
A strain gage is used to measure the strain, or local deformation, of an object. As the object deforms to stress, the gage also is deformed and its electrical resistance is changed. This change is then measured.
