A carbon resistance with color band is `2000 Omega`. If red band is replaced by green band then the new resistance is : (A) `500 Omega` (B) `300 Omega` (C) `400 Omega` (D) `100 Omega`

A 200 Omega resistor has a certain color code. If one replaces the red color by green in the code, the new resistance will be

The resistance of a colour-coded carbon resistance is 670 Omega . Find the colour of second band of the resistor.

A resistance of 2 Omega is connected across one gap of a meter bridge (the length of the wire is 100 cm and an unknown resistance, greater than 2 Omega , is connected across the other gap. When these resistance are interchanged, the balance point shifts by 20cm . Neglecting any corrections, the unknown resistance is. (a) 3 Omega (b) 4 Omega ( c) 5 Omega (d) 6 Omega .

How can three resistors of resistances 2 Omega,3 Omega , and 6 Omega be connected to give a total resistance of (a) 4 Omega (b) 1 Omega ?

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

A voltmeter of resistance 200 Omega is used to measure p.d across resistances 100 Omega and 200 Omega . .

Find the equivalent resistance when the following are connected in parallel: 1 Omega and 100 Omega and 1000 Omega
