Question

(a)Two identical resistors each of resistance 10 ohm are connected in
(1)series (2)parallel in turn to a battery or 6V. calculate the ratio of power consumed by the combination of resistor in the two cases.
(b) list two factors on which the resistance of a conductor depends
(c) write a difference and ammeter and voltmeter

Answer 1

in series power=1.8w
in parallel power=2.4w

b) length of conductor
nature of material
area of cross section of conductor
temperature
c) ammeter shows reading of current and connected in series
voltmeter shows reading of voltage applied
voltmeter is connected in parallel

*ask if have any doubt*
