Calculate the current flowing through a heater rated at `2 kW` when connected to a `300V` d.c. supply.

Answer

To calculate the current flowing through a heater rated at 2 kW when connected to a 300V d.c. supply, we can follow these steps:

### Step 1: Understand the given values
- Power (P) = 2 kW = 2000 W
- Voltage (V) = 300 V

### Step 2: Use the power formula
The power consumed by an electrical device is given by the formula:
\[ P = V \times I \]
where:
- \( P \) is the power in watts,
- \( V \) is the voltage in volts,
- \( I \) is the current in amperes.

### Step 3: Rearrange the formula to solve for current
To find the current (I), we can rearrange the formula:
\[ I = \frac{P}{V} \]

### Step 4: Substitute the known values
Now, substitute the known values into the equation:
\[ I = \frac{2000 \text{ W}}{300 \text{ V}} \]

### Step 5: Calculate the current
Now, perform the division:
\[ I = \frac{2000}{300} = 6.67 \text{ A} \]

### Conclusion
The current flowing through the heater is approximately **6.67 A**.
