According to Ohm's Law, what is the relationship expressed in the formula Volts = Amps x Resistance?

• A. Current is equal to voltage divided by resistance
• B. Power is equal to current times voltage
• C. Resistance is equal to voltage divided by current
• D. Voltage is equal to power times resistance

Answer: (C)

The relationship expressed in the formula Volts = Amps x Resistance reflects a fundamental principle of electrical circuits described by Ohm's Law. This law states that voltage (V) is directly proportional to the current (I) flowing through a conductor and the resistance (R) of that conductor. In algebraic terms, this law can be rearranged to demonstrate different relationships among voltage, current, and resistance. Choosing the correct relationship, where resistance is equal to voltage divided by current, is supported by this rearrangement of Ohm’s Law. When you have the equation Volts = Amps x Resistance, you can isolate resistance by dividing both sides of the equation by current (Amps). This manipulation yields the equation Resistance = Voltage / Current, confirming that if you know the voltage across a circuit and the current flowing through it, you can calculate the resistance. This understanding is crucial in electrical engineering and physics as it helps in analyzing circuit behavior under various conditions. Recognizing these relationships allows one to solve problems involving electrical components effectively and understand how they interact in a circuit.
