What happens when 2 charges are brought in contact? When two conductors are made to touch, the total charge on them is shared between the two. If the two conductors are identical, then each conductor will be left with half of the total charge. The electrostatic force determines the arrangement of charge on the surface […]

What is the importance of activation energy?
What is the importance of activation energy? All chemical reactions, including exothermic reactions, need activation energy to get started. Activation energy is needed so reactants can move together, overcome forces of repulsion, and start breaking bonds. What happens when activation energy increases? A higher activation energy means that the reaction will be slower. This is […]
Which multivibrators can be called a flip flop?
Which multivibrators can be called a flip flop? Bistable multivibrator What is the output of monostable multivibrator? A monostable multivibrator, also called a one shot or a monoflop, is a sequential logic electronic circuit that generates an output pulse. When triggered, a pulse of pre-defined duration is produced. The circuit then returns to its stable […]

How often does AC current change direction?
How often does AC current change direction? 60 times a second What is the use of reverse current? For constant temperatures, the reverse current is almost constant although the applied reverse voltage is increased up to a certain limit. Hence, it is also called reverse saturation current. The term is particularly applicable to mostly semiconductor […]
