If a device operates on 12 volts and draws 7 amps, what is the resistance of the circuit rounded to two decimal places?

To find the resistance of a circuit when the voltage and current are known, Ohm's Law is used, which states that the resistance (R) can be calculated using the formula:

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

where:

• ( V ) represents the voltage (in volts),

• ( I ) represents the current (in amperes).

In this case, the device operates on 12 volts, and it draws 7 amps. Plugging these values into the formula gives:

[ R = \frac{12 , \text{volts}}{7 , \text{amps}} ]

Calculating this results in:

[ R \approx 1.71428571428571 ]

Rounding this value to two decimal places gives approximately 1.71 Ohms. This is why the correct choice is identified as 1.71 Ohms, which accurately represents the resistance in the circuit given the parameters provided.
