What do you mean by logic gate?

Write the Boolean Expression of exclusive - OR (X-OP) gate.

Name the logic gate which generates high output when at least one input is high.

What is the phase difference between input signal voltage and output signal voltage in CE amplifier?

Capacity of a parallel capacitor with dielectric constant 5 is \(4 \mu F\). Calculate the capacity of the same capacitor when dielectric material is removed.

For the point P in above, we had to extend OC to Q to meet the perpendicular PQ. What will happen to the expression for I if the point P lies on OC?

What is the basis of Kirchhoff’s current law and voltage law?
