The melting point of Eureka is 1221 to 1300 °C
The melting point of Kanthal is 1,425 °C
The melting point of Nichrome is 1400 °C
The melting point of Graphite is 3,600°C
Hence Eureka has the least range of temperature.
A single-phase induction motor with only one winding on the stator cannot produce any starting torque. Hence, some extra arrangement is required to start the motor. In the running condition, the motor is capable of developing the torque with only one winding on the stator.
The simplest method of starting is to provide an auxiliary winding on the stator in addition to the main winding. The two windings are placed in the stator with their axes displaced by 90 electrical degrees in space.
The difference in level between points of supports and the lowest point on the conductor is called sag.
When the conductor is suspended between two supports at some level, it takes the shape of a catenary. However, if the sag is very small compared with the span, then the sag-span curve is like a parabola.
The tension at any point on the conductor acts tangentially. Thus tension To at the lowest point O acts horizontally.
In the exclusive OR gate (XOR gate) has two inputs
The ouput will be 1 when either input is 1 i.e X = 1 and Y = 1, but not when both the inputs are 1.
If both the input is zero i.e X = 0 and Y = 0, then the output is 0.
In the PMMC type instrument, the deflection is directly proportional to the current flowing through the instrument, we get a uniform scale for the instrument. It gives a uniform scale of upto 270° or more.
