A 4.5-volt battery sends an electrical current through a wire to a resistor. Resistance is measured in ohms (Ω). From the resistor, the current travels through another wire to an ammeter that measures the current in ampere units. The relationship among voltage (V), current (A), and resistance (Ω) is as follows:
Ω = V/A
If the ammeter measures the current at 0.3 amperes, what is the amount of the resistance?

15 ohms


The equation is as follows: Ω = V/A=4.5/0.3=15
