Question

Stu wanted to calculate the resistance of a light bulb connected to a 4. 0-v battery, with a resulting current of 0. 5 a. He used the formula r = vi and obtained an answer of 2. Was stu’s answer correct? how do you know?

Answer 1

no stus answer was incorrect

Step-by-step explanation:

The correct formula that relates current, resistance and voltage in a circuit is given by Ohm's law: or where V is the voltage in the circuitI is the current R is the resistanceIn this circuit, the voltage is V=4.0 V, and the current is I=0.5 A, therefore the resistance of the circuit is.
