Question

In a circuit the coil of a choke:

• A. Decreases the current
• B. Increases the current
• C. Has high resistance to D. C. circuit
• D. No effect with the current

Answer 1

The correct option is A Decreases the current

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.
