Respuesta

The resistance of the lamp is 3.0 ohms.

Explicación

## Step 1The problem involves the application of Ohm's law, which states that the current passing through a conductor between two points is directly proportional to the voltage across the two points. The formula for Ohm's law is given as:### where is the voltage, is the current, and is the resistance.## Step 2In this problem, we are given the current amperes and the voltage volts. We are asked to find the resistance .## Step 3To find the resistance, we rearrange the Ohm's law formula to solve for :### ## Step 4Substitute the given values into the formula:### ohms
