SUMMARY
The voltage of the battery in a circuit with a bulb, battery, and wires can be calculated using Ohm's Law, which states that Voltage (V) equals Current (I) multiplied by Resistance (R). In this case, with a current of 3 amperes and a resistance of 1.5 ohms, the voltage is determined to be 4.5 volts (V = I * R = 3 A * 1.5 Ω). This calculation confirms the direct relationship between voltage, current, and resistance in electrical circuits.
