What is the resistance in a circuit with 100VDC and 10A?

• A. 5 ohms
• B. 10 ohms
• C. 20 ohms
• D. 50 ohms

Answer: (B)

To determine the resistance in a circuit, Ohm's Law is utilized, which states that resistance (R) is equal to the voltage (V) divided by the current (I). In this problem, the circuit has a voltage of 100 volts (V) and a current of 10 amperes (A). Applying Ohm's Law: R = V / I Substituting in the provided values: R = 100V / 10A = 10 ohms Thus, the resistance in this circuit is 10 ohms, making it the correct answer. Understanding how to apply Ohm's Law is essential in calculating resistance, voltage, or current in electrical circuits. This foundational principle is critical in the field of electronics and electrical engineering.
