Answer:

The resistance of the device is 27Ω

Explanation:

When a device is used in a circuit in which the voltage is 81 V, the current flowing through the device is 3 A.

In order to calculate the resistance of the device, we know that the resistance is directly proportional to the voltage in the terminals of the device and the current flowing through it.

Using Ohm's law

$R=\frac{V}{I} \\R=\frac{81V}{3A}=27$ Ω
