Janet installed a dimmer on the lights in her bedroom. she slid the dimmer switch, causing the resistance in the circuit to decrease. assuming the voltage is constant, what affect will janet’s actions have on the circuit?

(a)the voltage will increase from 120 to 240 volts.
(b)the lights will brighten.
(c)the current will decrease.
(d)the current will increase.
(e)the lights will dim.

The correct answers are option(b) and(d).

Explanation:

When the lamp was dimmer  the resistance offered by the lamp was more which just resist the flow current from the circuit.

(Ohm's Law)

When the Janet decrease the resistance to (R') by sliding the dimmer switch (voltage remained constant). On decreasing the resistance the flow of current in circuit will increase by which light of the lamp will become brighter.

Hence, from the enlisted options the correct options option(b) and(d).

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
