When is a parallel combination used?

Two resistors 1k Omega and 3k Omega are connected in parallel combination. When this parallel combination is connected to 9 V supply, by neglecting internal resistance calculate current through each resistor.

When is a series combination used?

What is parallel combination ? With the help of diagram, explain its formula ?

Answer the following question: State the characteristics of a parallel combination of resistors.

Two resistors 1k Omega and 2k Omega are connected in parallel combination. Find equivalent resistance of parallel combination.

Answer the following. Derive the expression for equivalent resistance in parallel combination.

Choose correct alternative. Equivalent resistance in parallel combination is A. greater than the greatest resistance in the combination B. less than the least resistance in the combination C. average of all the resistors in the combination D. equal to sum of all the resistors in the combination

Choose the correct alternative and write it along its allotted alphabet: The effective resistance of a parallel combination of two resistors is 60 Omega and 40 Omega is ………..
