Question

series connection of cells series is advantageous only when the (a) effective internal resistance is negligibly small (b)effective internal resistance is large (c) effective external resistance is negligibly small (d) external resistance is infinity

Answer 1

Hey dear,

◆ Answer -

(a) effective internal resistance is negligibly small

◆ Explanation -

• Biggest factor affecting the efficiency of cell is its internal resistance.
• Lower the internal resistance, more efficient is the cell/battery.
• Therefore for battery to be advantageous, cells should be connected in series such that effective internal resistance is very small.

Thanks dear. Hope this helps you..
