An electric bulb draws 1.2 A current at 6V. Find the resistance of the filament of the bulb while glowing

Text Solution

AI Generated Solution

To find the resistance of the filament of the bulb while glowing, we can use Ohm's Law, which states that: \[ V = I \times R \] Where: - \( V \) is the voltage (in volts), - \( I \) is the current (in amperes), - \( R \) is the resistance (in ohms). ...
