Voltage is a measure of the electrical potential difference between two points in a circuit. In this case, we are interested in the voltage across the 5.0-Ω resistor.
Ohm’s Law states that the voltage across a resistor is directly proportional to the current flowing through the resistor and the resistance of the resistor. Mathematically, this can be expressed as:

- V is the voltage in volts (V)
- I is the current in amperes (A)
- R is the resistance in ohms (Ω)
In this case, we know the resistance of the resistor (5.0 Ω) and we can measure the current flowing through the resistor using a ammeter. Once we have these values, we can use Ohm’s Law to calculate the voltage across the resistor.
