Observe the given table. The truth table represents gate?

NAND
OR
XOR
AND

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 instruments has a uniform scale?

Moving iron type
Electrodynamic type
PMMC type
Dynamometer type

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

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.
Td ∝ I
