SSC JE Electrical 2019 with solution SET-2
Observe the given table. The truth table represents gate?

XOR
NAND
AND
OR

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

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.

Which of the following heating element has the lowest operating temperature?

Eureka
Kanthal
Graphite
Nichrome

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

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.

In an alternator, if α = 60°, then find the pitch factor?

0
1/2
1
√3/2

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

The factor by which, the induced E.M.F gets reduced due to short pitching is called pitch factor or coil span factor denoted by Kc. It is given as
Kc = cosα/2
given
α = 60°
Kc = cos60/2
Kc = cos30°
Kc = √3/2

While estimating the overhead lines, if the number of poles required is 14, then what is the estimated number of earth sets required?

2
4
5
3

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

While estimating the overhead lines, the first and last pole is always earth connected and after every 3rd electrical pole, the fourth pole is earthed. Therefore, the approximate number of required ground set = 4
