What is
(i) Conventional current
(ii) Electronic current ?

What do you mean by conventional current?

The current gain for common emitter amplifier is 69. If the emitter current is 7.0 mA , find (i) base current and (ii) collector current.

Mark the direction of conventional current flow and electrical charge flow in the diagram given below. Are they in the same direction?

(A) : The orbital magnetic moment and angular momentum of orbiting electron are always in opposite directions. (R) : Conventional direction of current flow is opposite to the direction of electron motion.

In a transistor, doping level in base is increased slightly. How will it affect (i) collector current and (ii)base current?

Assertion : When two semi conductor of p and n type are brought in contact, they form p-n junction which act like a rectifier. Reason : A rectifier is used to convent alternating current into direct current.

The direction of conventional current is in the opposite direction as that of electrical charge.

The diagram shows a circuit in which a bulb is connected through connecting the wires to a cell. If the bulb is glowing then what will be the direction of the conventional current in the circuit?

A conductor AB is joined to a cell with its end A at a low potential and the end B at a high potential. (a} State the direction of flow of electrons in it. (b) What will be the direction of flow of conventional current in the conductor?

What is the value of current I in given circuits (a)
