Question

Fatima connects ten 12 Ohm lamps in series. What is the total resistance of the circuit?
a ) 12 Ohm
b ) 1.2 Ohm
c ) 120 Ohm

Answer 1

Answer:

Explanation:

Effective resistance when the resistances are connected in series is the sum of all the resistances.

∴ $R_{eq}$ = 12 × 10 = 120 ohm

∴ (c)
