Choke is used to____
|
|
Convert AC to DC
|
|
|
Convert DC to AC
|
|
|
Reduce the current in AC circuit
|
|
|
Reduce the current in DC circuit
|
Explanation:
Detailed explanation-1: -A choke coil is preferred over resistance in a.c circuit because a choke coil has larger value of self inductance and hence power dissipation is zero for choke coil.
Detailed explanation-2: -A). Device to reduce current in DC circuit.
Detailed explanation-3: -The choke coil can be used only in ac circuits, not in dc circuits, because for dc(=0) the inductive reactance XL=L of the coil is zero, only the resistance of the coil remains effective which too is almost zero. Q.
