Two resistance connected in parallel across a cell of negligible internal resistance, use 4.5 times the power that they would use, when in series across the same cell. If one of the resistance is 8ohm, the other is:-

Two resistances , connected in parallel across a source of negligible interna resistance, consumes four times the power that they would consume when connected in series across the same source. If one of the resistances is 10 Omega the other is

Two unequal resistances are connected in parallel across a cell. True statement is

When 2 equal resistances are connected in parallel to the poles of a cell of negligible internal resistance, the power developed is P. When the same resistances are connected in series across the same cell, the power developed is

An ammeter and a voltmeter of resistance R are connected in series to an electric cell of negligible internal resistance . Their readings are A and V respectively. If another resistance R is connected in parallel with the voltmeter , then

A lead resistance R is connected across a cell of emf E and internal resistance r. If the closed circuit p.d. across the terminals of the cell is V the internal resistance of the cell is.

Four equal resistance dissipated 5 W of power together when connected in series to a battery of negligible internal resistance . The total power dissipated in these resistance when connected in parallel across the same battery would be .
