Adding a second battery in a single loop: #1 #1 1.5 V- 1.5 V 14 1.5V 4 Predicted V- _5 volts Predicted Effect of the Modification: (same as before, less than before, greater than before) Predicted V,3 D volts Potential difference across Bulb #1 : Electric Brightness of Bulb #1 (as reflected in visible bulb brightness) ctual Effect of the Modification on the brightness of Bulb #1Explanation / Answer
1.
adding a bulb in series , increases the total resistance of the circuit. hence the current in the circuit decrease. as the current decrease, the potential difference across bulb 1 decrease.
electric current also decrease in bulb 1
brightness of the bulb also decrease since the potential difference across the bulb decrease.
