Question
In a circuit the current the coil of a choke :
Options
A.decreases the current
B.increasesthe current
C.has high resistance to D.C. circuit
D.no effect with
Solution
In a circuit with a.c. source choke coil which is essentially an inductor with high reactance, is used to decrease the current without loss of energy. No heat is generated so no loss of energy. When we use resistance to reduce current there is loss of electrical energy in the form of heat generated.
