You have a wire with an unknown resistance, and you want to determine its resistance using Ohm’s law. You’re provided with the following information:
• Voltage across the wire (V ) = 12 volts
• Current passing through the wire (I) = 2.5 amperes
Using Ohm’s law (V = I · R), calculate the resistance of the given wire.

Option: 1

4.8 ohms 


Option: 2

3.4 ohms


Option: 3

2.6 ohms


Option: 4

5.9 ohms

Use Ohm’s law to calculate the resistance (R):

V = I · R ..................(1)

Solve for R: 

R=\frac{V}{I} = \frac{12}{2.5} = 4.8 ohms .......(2)

 

 Therefore, the resistance of the given wire is 4.8 ohms. Therefore, the correct option is (A).
