Ash is working in the lab, and comes across a box ofunlabeled resistors (thanks to his messy coworker whonever puts them back properly).He remembers that he can find out the resistance using anammeter to measure current, and a battery with a knownvoltage.Ash picks a resistor of unknown resistance (in), connectsit to some wires, and then plugs in a battery with a voltageof 32.2 V. This creates a circuit. Using the ammeter, hefinds that the current in the circuit is 3 A.In ohms, what is the resistance of the unknown resistor?Answer:Ω.

Current is Voltage is Find:Resistance of unknown resistor.

Ash picks a resistor of unknown resistance (in 2), connects it to some wires, and then plugs in a battery with a voltage of 32.2 V. This creates a circuit. Using the ammeter, he finds that the current in the circuit is 3 A.
