Three resistance, 2 Ω Ω , 4 Ω Ω , 5 Ω Ω are combined in series and this combination is connected to a battery of 12V emf and negligible internal resistance. The potential drop across these resistances are
Text Solution
Verified by ExpertsThe correct answer is:
D

Let current in the circuit is I. Then total resistance in the circuit

V = IR

The potential drop across
resistance

The potential drop across
resistance

The potential drop across
