Final answer:
The resistance of a resistor through which a specific current is flowing can be determined using Ohm's law, provided the voltage is known. For resistors in series, total resistance is the sum of individual resistances. The voltage across a resistor is calculated as the product of the resistance and the current.
Step-by-step explanation:
The value of a resistor can be calculated using Ohm's law, which states that the voltage (V) across a resistor is the product of the current (I) flowing through it and its resistance (R), expressed as V = IR. When 0.375 A of current moves across a resistor, you need the voltage to find the resistance. If you have 10 resistors R connected in a series and 0.005 A of current flows through the circuit, the total resistance (Rtotal) of these resistors will be 10 times the resistance of one resistor, since resistances add up in series. The voltage across a resistor can be found using the same Ohm's law. For example, if the current through a 10-ohm resistor is 0.025 A, the voltage drop across the resistor is 0.025 A * 10 Ω = 0.25 V.
