V = I + R
V = I - R
V = I * R
V = I / R
Questions & Step-by-Step Solutions
What is the relationship between voltage, current, and resistance in a circuit according to Ohm's Law?
Correct Answer: V = I * R
Step 1: Understand the terms: Voltage (V) is the electrical force, Current (I) is the flow of electricity, and Resistance (R) is the opposition to the flow.
Step 2: Remember the formula from Ohm's Law: V = I * R.
Step 3: This formula means that Voltage equals Current multiplied by Resistance.
Step 4: If you know any two of these values (V, I, R), you can find the third one using the formula.
Step 5: For example, if you have a Voltage of 10 volts and a Resistance of 2 ohms, you can find the Current by rearranging the formula to I = V / R, which gives you 5 amps.
