When are resistors said to be connected in parallel ?

When two resistors of R value connected in parallel what is equivalent resistance '?

A set of n identical resistors, each of resistance R Omega , when connected in series have an effective resistance X Omega and when the resistors are connected in parallel, their effective resistance is Y Omega . Find the relation between R, X and Y.

Three equal resistors connected across, a source of emf together dissipate 10 watt of power. What will be the power dissipated in watt if the same resistors are connected in parallel across the same source of emf

First a set of n equal resistors of R each are connected in series to a battery of emf E and internal resistance R. A current I is observed to flow. Then the n resistors are connected in parallel to the same battery. It is observed that the current is increased 10 times. What is 'n'?

Three resistors are connected in parallel with a 30V battery. A current of 7.5A flows through the circuit. If two out of the three resistors are of 10Omega and 12Omega , determine the resistance of the third resistor.

Obtain the expression for the equivalent resistance for 3 resistors connected in parallel and also write the expression of equivalent resistance for connection of' n' resistors.

A set of 'n' equal resistors, of value 'R' each, are connected in series to a battery of emf 'E' ,and internal resistance 'R'. The current drawn is I. Now, the 'n' resistors arc connected in parallel to the same battery. Then the current drqwn from battery becomes 10 I. The value of 'n' is
