What can be calculated using the formula I = E ÷ R?

• A. Ampere
• B. Voltage
• C. Power
• D. Resistance

Answer: (A)

The formula I = E ÷ R is derived from Ohm's Law, where I represents current in amperes, E represents voltage in volts, and R represents resistance in ohms. This equation shows that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor. Thus, this formula can be used specifically to calculate the current, measured in amperes. When voltage (E) is divided by resistance (R), the resulting value is the current (I) in ampere units. This fundamental relationship is essential for understanding electrical circuits and how they behave under various conditions. Voltage, power, and resistance can all be calculated using other forms of Ohm's Law or related electrical equations, but in this specific context of I = E ÷ R, the calculation explicitly yields the current in amperes.
