Observe the given table. The truth table represents gate?

XOR
OR
AND
NAND

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.

Observe the given figure. If the diode is an ideal diode, then what are the values of Io and Vo respectively?

0.2 A, 0V
0 A, 0.2 V
2 A, 10 V
10A, 2 V

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Io = V/R = 20/100
Io = 0.2 A
Since the given diode is an ideal diode therefore there is no voltage drop across it.
Vo = Io × RD
Vo = 0.2 × 0
Vo = 0
Hence Io = 0.2 A & Vo = 0
