Question

What is the correct calculation for resistance when the current is 4 amps and the voltage is 24 volts?


24 volts + 4 amps = 28 ohms

24 volts × 4 amps = 96 ohms

24 volts ÷ 4 amps = 6 ohms

24 volts – 4 amps = 20 ohms

Answer 1

The correct calculation for resistance (using Ohm's law) is given by the formula:

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

where:
- \( R \) is the resistance in ohms (Ω),
- \( V \) is the voltage in volts (V),
- \( I \) is the current in amps (A).

In your case, using the values provided:

- Voltage \( V = 24 \) volts
- Current \( I = 4 \) amps

Now, substituting the values into the formula:

\[ R = \frac{24 \text{ volts}}{4 \text{ amps}} = 6 \text{ ohms} \]

So, the correct answer is:

**24 volts ÷ 4 amps = 6 ohms**
