If a heater operates at 240 volts and has a resistance of 28 ohms, what is the current flowing through the circuit?

If a heater operates at 240 volts and has a resistance of 28 ohms, what is the current flowing through the circuit?

• A. 5.71 A
• B. 8.57 A
• C. 10.85 A
• D. 7.43 A

Answer: (B)

To determine the current flowing through a circuit when given the voltage and resistance, you can apply Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). The formula can be expressed as: \[ I = \frac{V}{R} \] In this scenario, the heater operates at 240 volts and has a resistance of 28 ohms. Plugging these values into the formula gives: \[ I = \frac{240 \text{ volts}}{28 \text{ ohms}} \] Calculating that: \[ I = 8.57 \text{ A} \] This means that the current flowing through the circuit is 8.57 amperes. This value aligns with the correct answer option, making it the accurate calculation based on the parameters provided. If you were to explore the other options, they do not match the result obtained from applying Ohm's Law with the values given in the question, confirming that the selected answer is the correct one.

To determine the current flowing through a circuit when given the voltage and resistance, you can apply Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). The formula can be expressed as:

[ I = \frac{V}{R} ]

In this scenario, the heater operates at 240 volts and has a resistance of 28 ohms. Plugging these values into the formula gives:

[ I = \frac{240 \text{ volts}}{28 \text{ ohms}} ]

Calculating that:

[ I = 8.57 \text{ A} ]

This means that the current flowing through the circuit is 8.57 amperes. This value aligns with the correct answer option, making it the accurate calculation based on the parameters provided.
