A lamp has a current of 2.0 amperes at 6.0 volts. What is the resistance of the lamp? 15 ohms 3.0 ohms 6.0 ohms 12 ohms

## Step 1<br />The 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:<br />### \( V = IR \)<br />where \( V \) is the voltage, \( I \) is the current, and \( R \) is the resistance.<br /><br />## Step 2<br />In this problem, we are given the current \( I = 2.0 \) amperes and the voltage \( V = 6.0 \) volts. We are asked to find the resistance \( R \).<br /><br />## Step 3<br />To find the resistance, we rearrange the Ohm's law formula to solve for \( R \):<br />### \( R = \frac{V}{I} \)<br /><br />## Step 4<br />Substitute the given values into the formula:<br />### \( R = \frac{6.0}{2.0} = 3.0 \) ohms
