The cell potential of a battery is measured at 2.25 V connected to a bulb that have resistance of 3 ohms. (a) Determine the current. (b) The bulb was change with a new bulb with resistance of 1.5 ohms. What is the cell potential if the current remains the same?
Added by Jonathan M.
Step 1
25V and the resistance of the bulb is 3 ohms. Given: Cell potential (V) = 2.25V Resistance (R) = 3 ohms Use Ohm's Law to calculate the current (I): \[ I = \frac{V}{R} \] \[ I = \frac{2.25}{3} \] \[ I = 0.75 A \] ** Show more…
