If the effective resistance is to be increased then the number of resistors should be connected in......... ​

Answer 1

Answer:

If the effective resistance is to be increased then the number of resistors should be connected in series.

Answer 2

If the effective resistance is to be increased then the number of resistors should be connected in series.

• When a succession of resistances is linked, the equivalent resistance is maximal and the current flow is minimal.
• The equivalent resistance in a series combination is the total of the individual resistances, but the equivalent resistance in a parallel combination is the sum of the reciprocal of the individual resistances.
• As a result, when resistors are joined in series, their effective resistance increases.
• The current flow decreases as the effective resistance increases. This is because of Ohm's law.
