What is the current flowing through a 100-ohm resistor connected across 200 volts?

• A. 20,000 amperes
• B. 0.5 amperes
• C. 2 amperes
• D. 100 amperes

Answer: (C)

To determine the current flowing through a resistor, Ohm's Law is applied, which states that the current (I) is equal to the voltage (V) divided by the resistance (R). In this case, the voltage provided is 200 volts, and the resistance is 100 ohms. Using the formula: I = V / R Substituting the known values: I = 200 volts / 100 ohms = 2 amperes This calculation shows that the current flowing through the 100-ohm resistor is indeed 2 amperes. Understanding Ohm's Law is fundamental in electronics, as it allows one to analyze and calculate electrical circuits effectively. In this scenario, knowing the values of voltage and resistance directly leads to calculating current efficiently and accurately.
