A heater coil is cut into two parts of equal length and one of them is used in the leader. The ratio of the heat procued by this half coil to that by the original coil is

Options

A. `2:1`
B. `1:2`
C. `1:4`
D. `4:1`

Explanation

To solve the problem of finding the ratio of heat produced by half of the heater coil to that produced by the original coil, we can follow these steps:

### Step 1: Understand the relationship between power, resistance, and heat produced.
The heat produced (H) in a resistor (or coil) is given by the formula:
\[ H = P \times t \]
where \( P \) is the power and \( t \) is the time for which the power is applied.

### Step 2: Relate power to resistance.
