What is the current through a 24-ohm resistor connected across 240 volts?

• A. 10 amperes
• B. 5 amperes
• C. 12 amperes
• D. 8 amperes

Answer: (A)

To determine the current flowing through a 24-ohm resistor connected to a voltage of 240 volts, Ohm's Law can be applied. Ohm's Law states that the current (I) in amperes is equal to the voltage (V) in volts divided by the resistance (R) in ohms. So the formula is: \[ I = \frac{V}{R} \] In this case, the voltage (V) is 240 volts and the resistance (R) is 24 ohms. Substituting these values into the formula gives: \[ I = \frac{240 \text{ volts}}{24 \text{ ohms}} = 10 \text{ amperes} \] Thus, 10 amperes is indeed the current flowing through the 24-ohm resistor when subjected to a voltage of 240 volts. This calculation confirms that the correct answer is valid based on the application of basic electrical principles.

So the formula is:

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

In this case, the voltage (V) is 240 volts and the resistance (R) is 24 ohms.

Substituting these values into the formula gives:

[ I = \frac{240 \text{ volts}}{24 \text{ ohms}} = 10 \text{ amperes} ]

Thus, 10 amperes is indeed the current flowing through the 24-ohm resistor when subjected to a voltage of 240 volts. This calculation confirms that the correct answer is valid based on the application of basic electrical principles.
