Question

Based on the circuit voltage and the wattage consumption,determine the approximate ampere rating of the followingappliances. Remember amps = watts divided by voltage.a = w÷ VRound to the nearest whole amp.1. AC Compressor on a 240 volt line and using 5,000 watts, amps =_____2. baseboard heater on a 120 volt line and using 1,200 watts, amps =_____3. vacuum cleaner on a 120 volt line and using 500 watts, amps =______4. blender on a 115 volt line and using 300 watts, amps5. toaster on a 120 volt line using 1,100 watts, amps =_____

Answer 1

Given:

1.

The voltage of AC compressor is V = 250 V

The power of the AC compressor is P = 5000 W

2.

The voltage of the baseboard heater is V = 120 V

The power of the baseboard heater is P = 1200 W

3.

The voltage of the vacuum cleaner is V = 120 V

The power of the vacuum cleaner is P = 500 W

4.

The voltage of the blender is V = 115 V

The power of the blender is P = 300 W

5.

The voltage of the toaster is 120 V

The power of the toaster is P = 1100 W

Required:

1. The approximate ampere rating of the AC compressor.

2. The approximate ampere rating of the baseboard heater.

3. The approximate ampere rating of the vacuum cleaner.

4. The approximate ampere rating of the blender.

5. The approximate ampere rating of the toaster.

Step-by-step explanation:

1. The approximate ampere rating of the AC compressor can be calculated as

`\begin{gathered} I\text{ = }(P)/(V) \\ =(5000)/(240) \\ =20.833\text{ A} \\ \approx21\text{ A} \end{gathered}`

2. The approximate ampere rating of the baseboard heater can be calculated as

`\begin{gathered} I=(1200)/(120) \\ =\text{ 10 A} \end{gathered}`

3. The approximate ampere rating of the vacuum cleaner can be calculated as

`\begin{gathered} I\text{ = }(500)/(120) \\ =4.2\text{ A} \\ \approx4\text{ A} \end{gathered}`

4. The approximate ampere rating of the blender can be calculated as

`\begin{gathered} I\text{ =}(300)/(115) \\ =2.6\text{ A} \\ \approx3\text{ A} \end{gathered}`

5. The approximate ampere rating of the toaster can be calculated as

`\begin{gathered} I\text{ =}(1100)/(120) \\ =9.2\text{ A} \\ \approx\text{ 9 A} \end{gathered}`

Final Answer:

1. The approximate ampere rating of the AC compressor is 21 A.

2. The approximate ampere rating of the baseboard heater is 10 A.

3. The approximate ampere rating of the vacuum cleaner is 4 A.

4. The approximate ampere rating of the blender is 3 A.

5. The approximate ampere rating of the toaster is 9 A.
