If a circuit is supplied with 100 volts and has a total resistance of 200 ohms, what is the current drawn by the circuit?

• A. 0.5 amps
• B. 2 amps
• C. 4 amps
• D. 20 amps

Answer: (A)

To determine the current drawn by a circuit, you apply Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). In this case, the circuit is supplied with 100 volts and has a total resistance of 200 ohms. Using the formula: \[ I = \frac{V}{R} \] you can plug in the values: \[ I = \frac{100 \text{ volts}}{200 \text{ ohms}} \] This simplifies to: \[ I = 0.5 \text{ amps} \] This calculation shows that the current drawn by the circuit is indeed 0.5 amps. This outcome reflects an understanding of both Ohm's Law and the relationship between voltage, current, and resistance in electrical circuits, which is fundamental in electrical troubleshooting and analysis.

Using the formula:

[ I = \frac{V}{R} ]

you can plug in the values:

[ I = \frac{100 \text{ volts}}{200 \text{ ohms}} ]

This simplifies to:

[ I = 0.5 \text{ amps} ]

This calculation shows that the current drawn by the circuit is indeed 0.5 amps. This outcome reflects an understanding of both Ohm's Law and the relationship between voltage, current, and resistance in electrical circuits, which is fundamental in electrical troubleshooting and analysis.
