An electric heater is connected to DC and AC sources of equal voltage turn by turn. In which case (AC or DC) the rate of heat production will be more ?

Explanation

To determine in which case (AC or DC) the rate of heat production will be more when an electric heater is connected to both sources of equal voltage, we can analyze the heat production using the formula for electrical power.

### Step-by-Step Solution:

1. **Understanding Power in DC Circuits**:
- For a DC circuit, the power (P) consumed by the heater can be calculated using the formula:
\[
P_{DC} = \frac{V^2}{R}
