series and parallel combination problem in tamil

A resistors of 10 ohm is connected in series with two resistors each of 15 ohm arranged in parallel,What resistance must be shunted across the combination so that the total current taken is 1.5amp with 20 applied.


Two resistances in parallel:
This equation must be used when finding the total resistance R of a parallel circuit.
For the special case of two resistors in parallel.

Resistors in Parallel:
The circuit in which similar ends are connected together is called as parallel circuit. In the given circuit R1, R2 and R3 are connected in parallel.

There are many separate paths for current flow. The voltage across all parallel branches is the same. Current in each branch is different and depends on the value of resistance in the branch.
