Three resistors of 3 ohms, 5 ohms, and 22 ohms are connected in series in a 28-volt circuit. How much current will flow through the 3-ohm resistor?

Explanation:
In a series circuit, the same current flows through every component, and the total resistance is the sum of the individual resistances. Add the resistors: 3 + 5 + 22 = 30 ohms. With a 28-volt supply, the current is I = 28 / 30 ≈ 0.933 A. Since the current is the same through all parts of a series circuit, the 3-ohm resistor also carries about 0.933 amperes (approximately 0.93 A).
