Resistivity & Temperature || Colour Code OF Resistances

A 200 Omega resistance has a certain colour code as per standard colour coding. If one replaces the red colour by green in the code, the new resistance will be

The resistance of a potentiometer wire of length 10 m is 20 Omega . A resistance box and a 2 volt accumulator are connected in series with it. What resistance should be introduced in the box to have a potential drop of one microvolt per millimetre of the potentiometer wire ?

A 2 volt battery, a 15 Omega resistor and a potentiometer of 100 cm length, all are connected in series. If the resistance resistance of potentiometer wire is 5 Omega , then the potential gradient of the potentiometer wire is

The given potentiometer has its wire of resistance 10 Omega When the sliding contact is in the middle of the potentiometer wire, the potential drop across 2 Omega resistor is :
