Question
Download Solution PDFWhat is the value of equivalent resistance if the resistor 10 Ω is parallel to 20 Ω?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 3 i.e. 6.67Ω
Concept :
Resistance in Parallel :
- In this parallel connection, the end terminals of all resistances are connected to the same two nodes.
- The voltage drop across all resistances is the same.
- RAB = R1 || R2 || R3 ............... || Rn
Calculation :
Let RAB is an equivalence resistance of 10 Ω and 20 Ω which is connected in parallel.
RAB =
Additional Information Resistance in Series:
- In this series connection, all resistances are connected in a single line by an end-to-end.
- The current is the same in all resistances.
- RAB = R1 + R2 + R3 + .................. + Rn
