In a series circuit with E = 3 volts and R = 3 ohms, the current is ______ amps?

Explanation:
Current is determined by Ohm's law: I = V / R. With a 3-volt source across a 3-ohm resistor, the current is I = 3 / 3 = 1 amp. In a series circuit, the same current flows through every element, and since there’s only one resistor here, the circuit current is 1 A.
