If the potential difference of 1 volt is applied across the end of a conductor and the current flowing through the conductor is one ampere, then the resistance of the conductor is said to be?
Correct answer: C. 1 Ohm
- A. 1 Farad
- B. 10 Coulomb
- C. 1 Ohm
- D. 1 Coulomb
- E. 10 Ohm
Explanation
Potential difference=V=1 volt Current=I=1 Ampere According to Ohm's Law: V=IR Resistance R = Voltage V/ Current I R=1 volt / 1 Ampere R=1 ohm , so option C is correct. As this question is theoretical, options A, B,D and E are all incorrect

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
