A current of 1 ampere flow in a series circuit contain an electric lamp and a conductor of 5 ohm when connected to a 10 watt battery. calculate the resistance |
Answer» ➠ ANSWER :-➝ Case 1 :➝ given :-
Total Resistance in the series = 5+R we know that → I = V/R → I = 10/(5+R) ➝ Case 2:As the resistance are in parallel series so, Total Resistance = (R¹ × R² )/( R¹+R²) → I = V/R → I = 10/5 → I = 2 Amp CURRENT in each branch = 2/2 = 1 (both of the branches have same resistance and because of it the current is DIVIDED equally.) POTENTIAL across the LAMP+ Conductor = 10V Potential across the lamp = 5 V |
