If a circuit contains a voltage of 50 volts and uses a resistance of 10 ohms, what is the current in the circuit?

  1. 5 Amperes

  2. 10 Amperes

  3. 2 Amperes

  4. 20 Amperes

The correct answer is: 5 Amperes

To find the current in a circuit when the voltage and resistance are known, you can use Ohm's Law, which states that the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R). In this case, the voltage is 50 volts and the resistance is 10 ohms. Applying Ohm's Law: I = V / R Substituting the given values: I = 50 volts / 10 ohms = 5 Amperes Thus, the calculation shows that the current flowing through the circuit is 5 Amperes, confirming that this option is indeed the correct answer. Understanding how to apply Ohm’s Law is fundamental in analyzing electrical circuits, as it allows for determining the relationship between voltage, current, and resistance effectively.
