Correct option is A
The correct answer is (a) 1 ampere
Explanation:
. Ohm’s Law states that V = I × R.
. Rearranging, R = V / I.
. Given R = 1 ohm and V = 1 volt.
. Substituting values, 1 ohm = 1 volt / 1 ampere.
. Hence, the blank is correctly filled by 1 ampere.
Information Booster:
. Ohm is the SI unit of electrical resistance.
. One ohm is defined as the resistance which allows a current of one ampere when one volt is applied.
Additional Knowledge:
1/2 ampere (Option b)
. This would make resistance equal to 2 ohms for 1 volt.
. Hence, incorrect.
2 ampere (Option c)
. This would correspond to resistance of 0.5 ohm.
. Therefore, incorrect.
30.5 ampere (Option d)
. Such a large current implies extremely low resistance.
. It is not consistent with 1 ohm resistance.
