What will the resultant resistance be if five 0.2 ohm resistances are linked in series?

Answer:

The cumulative resistance of any number of resistances connected in series equals the individual resistances, according to the law of series combination of resistances.

R = R1 + R2 + R3 + R4 + R5

R = 0.2 + 0.2 + 0.2 + 0.2 + 0.2 = 1 ohm
