combination of resistance 1

A potential divider is used to given outputs of 2V and 3V form a 5V source, as shown in fig. Which combination of resistance R_1, R_2, and R_3 gives the correct voltages?

The equivalent resistance between point A and B for the combination of resistance

(a) what is meant by series and parallel combination of resistances ? (b) in which case, series combination or parallel combination, the combined resistance is less than any of the individual resistances ? (c ) How should two resistance of 2 Omega each be connected so as to produce an equivalent resistance of 1 Omega ? In the circuit diagram given here , find: (i) total resistance of the circuit (ii) total current flowing in the circuit, and (iii) the potential difference across R_(1)

Combination of Resistance (Potential method And infinite )

A carbon and an aluminimum wire are connected in series.If the combination has resistance of 27 ohm at 0^(@)C ,what is the resistance of each wire at 0^(@)C so that the resistance of the combination does not change with temperature ? [alpha_(C ) = -0.5 xx 10^(-3)(.^@C)^(-1) and alpha_(A) = 4 xx 10^(-3)(.^@C)^-1] .
