For a best choke coil incorrect statements are :-
(a) Low resistance, high inductance
(b) Power factor is very less
(c) Consumes very - less power
(d) Based on watt less current

Options

A. a,b
B. b,c
C. c,d
D. None of these

Answer

To determine the incorrect statements regarding a choke coil, we need to analyze each option based on the properties of choke coils.

### Step-by-Step Solution:

1. **Understanding Choke Coil**:
A choke coil is an inductor used to limit the current in an AC circuit. It has a certain resistance (R) and inductance (L). The main purpose of a choke coil is to drop voltage while minimizing power loss.

2. **Analyzing Each Statement**:
- **(a) Low resistance, high inductance**:
This statement is correct. For a choke coil to function effectively, it should have low resistance to minimize power loss and high inductance to ensure a significant voltage drop across it.

- **(b) Power factor is very less**:
This statement is also correct. A choke coil is designed to have a low power factor (cos φ) to reduce power loss. A low power factor indicates that the circuit consumes less real power compared to the apparent power.

- **(c) Consumes very less power**:
This statement is correct as well. A choke coil is designed to minimize power consumption while still allowing the necessary current to flow through the circuit.

- **(d) Based on watt less current**:
This statement is incorrect. The term "watt less current" suggests that the current is zero or that there is no real power being consumed, which is not true for a choke coil. While it minimizes power loss, it does not mean that the current is wattless.

3. **Conclusion**:
The incorrect statement among the options provided is **(d) Based on watt less current**.

### Final Answer:
The incorrect statement regarding a choke coil is **(d) Based on watt less current**.
