5 A
Correct Answer: 0.5 A
Exam Year: 2022
Solution:
Using Ohm\'s law, I = V/R = 5 V / 10 ohms = 0.5 A.

If the resistance of a circuit is 10 ohms and the induced EMF is 5 V, what is the induced current? (2022)
Step 1: Identify the values given in the problem. The resistance (R) is 10 ohms and the induced EMF (V) is 5 volts.
Step 2: Recall Ohm's law, which states that current (I) is equal to voltage (V) divided by resistance (R). The formula is I = V / R.
Step 3: Substitute the values into the formula. Replace V with 5 volts and R with 10 ohms: I = 5 V / 10 ohms.
Step 4: Perform the division. Calculate 5 divided by 10, which equals 0.5.
Step 5: State the result. The induced current (I) is 0.5 amperes (A).
Ohm's Law – Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor.
