Paper capacitor

Boolean expression for AND operation is:

X = A . B

X = A?

X = A + B

X = A?B?

The digits used in electronics are:

1

0

1 and 2

0 and 1

A and B are the two inputs of a NOR gate. Its output would be 1 when:

A = 0 , B = 1

A = 1, B = 0

A = 0 , B = 0

A = 1, B = 1

The output of a NAND gate is 0 when

Both of its inputs are 1

any of its inputs is 0

Both of its inputs are 0

any of its inputs is 1

electric intensity is a quantity:

vector

scalar

none of these

base
