Analogues of chock coil in DC is:
Correct answer: A. Rheostat
- A. Rheostat
- B. Potential divider
- C. Thermistor
- D. Resistor
Explanation
In AC circuits, a choke coil is used to limit the current without causing a significant loss of energy, thanks to its inductive properties. In DC circuits, a rheostat performs a similar function by providing variable resistance and thereby controlling the current flow. While a potential divider manages voltage and a thermistor responds to temperature changes, neither functions like a choke coil in controlling current. A simple resistor also lacks the variable control necessary to be an analogue to a choke coil.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
