Three resistance of one ohm each are connected in parallel. Such connection is again connected with 2//3 Omega resistor in series. The resultant resistance will be

The equivalent resistance of a group of resistance is R . If another resistanceis connected in parallel to the group, its new equivalent becomes R_(1) and if it is connected in series to the group, it new equivalent bemomes R_(2) we have

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
