How to Calculate the Current in a Light Bulb?
What is the current in a light bulb connected to a 1.5V battery with a resistance of 3.5?
Since you haven't mentioned the units of the 3.5, we'll assume it's in ohms. How can we calculate the current in the bulb?
Calculation of Current in Light Bulb:
To calculate the current in the light bulb, we can use Ohm's Law formula: Current = Voltage / Resistance.
When a 1.5V battery is connected to a light bulb with a resistance of 3.5 ohms, we can find the current flowing through the bulb by applying Ohm's Law.
Given values:
Voltage (V) = 1.5V
Resistance (R) = 3.5 ohms
Current (I) = Voltage (V) / Resistance (R)
Substitute the values into the formula:
I = 1.5V / 3.5 ohms
Calculating the current, we get:
I ≈ 0.43 Amperes
Explanation:
By dividing the voltage by the resistance, we determined that the current flowing through the light bulb is approximately 0.43A.
Therefore, the current in the bulb connected to a 1.5V battery with a resistance of 3.5 ohms is around 0.43 Amperes.
