Show answer Hide answer
(i) False. (ii) True. (iii) False.

Explanation

  • (i) Dry cells are more portable than Voltaic cells, not less.
  • (ii) A coil acts as an electromagnet only while current flows.
  • (iii) Two cells give more current, so they attract more clips than one cell.
More current means a stronger electromagnet, not a weaker one.
