Ohm's Law can be used to calculate which of the following?

Ohm's Law is a fundamental principle in electrical engineering that defines the relationship between voltage (V), current (I), and resistance (R) in a circuit. The law states that the current 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. Mathematically, it is expressed as V = I × R.

This relationship allows for a variety of calculations in electrical circuits:

1. Power Consumption: Ohm's Law can help calculate power (P) because power can be expressed in terms of voltage and current using the formula P = V × I. By rearranging Ohm's Law, you can find voltage or current, which can then be used to compute power.

2. Voltage Drop: The voltage drop across a resistor in a circuit can also be calculated using Ohm's Law. By knowing the current flowing through the resistor and its resistance, you can determine the voltage drop across it. This is crucial for understanding how voltage is distributed in a circuit.

3. Resistance: Ohm’s Law allows for the calculation of resistance if the voltage and current are known. By rearranging the formula, you can express resistance as R
