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.
4.8 ohms
3.4 ohms
2.6 ohms
5.9 ohms
Use Ohm’s law to calculate the resistance (R):
V = I · R ..................(1)
Solve for R:
Therefore, the resistance of the given wire is 4.8 ohms. Therefore, the correct option is (A).
