Final answer:
The resistance of the bulb connected to a 1.5-volt battery and drawing a 3A current is calculated using Ohm's Law as 0.5 ohms.
Step-by-step explanation:
The resistance of a bulb through which a current is flowing can be calculated using Ohm's Law, which is stated as V = IR, where V is the voltage, I is the current, and R is the resistance. In the case mentioned, where a 1.5-volt battery is connected to a bulb and the current flowing through the bulb is 3A, we can rearrange the formula to solve for the resistance (R) by dividing the voltage (V) by the current (I).
So the resistance (R) is given by R = V / I. Substituting the given values, we would calculate the resistance as:
R = 1.5 volts / 3 amperes = 0.5 ohms. Therefore, the resistance of the bulb is 0.5 ohms.
