the condsumed electric current energy and electric current

Question 1

diff electric energy consumed

Answer 1

it the power per sec

Question 2

diff power

Answer 2

it is the electric energy consumed per sec

Question 3

all rule about electric energy consumed and all unit about this rule

Answer 3

VxQ unit Joule or VOLT x Q

V x I x t unit VOLT x AMP x sec

I² x R x t unit AMP² x OHM x sec

V² x t \ R

Question 4

alll rule and unit about power

Answer 4

elctric energy consumed \ sec unit joule\ sec

V x I x t unit VOLT x AMP

I2 x R unit AMP2 x OHM

V2 \ R

Question 5

when power directly proprthonal with resistance

and when power inverdly proprthonal with resistance

Answer 5

connected in series I²xR I is constant

conected in parallel V²xR V is constant

Question 6

the electric energy consumed increases in our houses if more lamp is switched on

Answer 6

in our houses the voltage is constant 220 and all lamps and insturment are connected in parallel so by switching on morw lamp ( nadding more resistoer in parallel ) the total resistance decreases

Pw = electric energy consumed \ t = VxI = V²\R

Pw & 1 \ R at constant v

Question 7

thick wire is used to connected nhoigh power air conditioner in your house

Answer 7

Pw = IxV Pw & I as the voltage is constant 220

R= PxL\A R & 1\A at constant other factor

so thick wire of low resistance shoild be used to carry strong current without being melt affected by the heat prodused from the ohmic resistance

Question 8

why electric fuse must be used in our houses

Answer 8

Pw = IxV I &Pw at the voltage 220 volt

to protect the electric circuit from damage if the electric current increases more than the safety limt

Question 9

two lamps lamp₁ has 20 ohm lamp₂ has 10 ohm conected in series which lamp is give more brightnees and why

Answer 9

LAMP₁

because it concted in series so the electric current constant and from the relation Pw = I²xR Pw & R

Question 10

two lamps lamp1 has 20 ohm lamp2 has 10 ohm conected in parallel which lamp is give more brightnees and why

Answer 10

LAMP₂

because it concted inparallel sopotenstial difference between two point constant and from the relation Pw = V² \R Pw & 1 \ R

Question 11

three identical lamp each of resistance (R) are concted with battery 9 volt one times they are connected in series and anthoer time in parallel in which case the lamp are more bright

consumed more energy and why

Answer 11

the lamps will be dim when they are conncted in series as their

Question 12

thick wire is used to connect a high power air conditioner in our house GR

Answer 12

P_w = I x V

I & P_w as the voltage is constant 220 volt

SO thick wire should used to meet the strong current by small resistance

Question 13

the electric power ( or electric energy ) consumed increases by increasing resistance if you able to make the current remain constant

Answer 13

P_w = E.energy consumed \ t = VxI = I²xR ⇒ P_w & R at constant [I]

Question 14

the electric power ( or electric energy ) consumed increases by decreases resistance if it is connected to the same electric source GR

Answer 14

P_w = E.energy consumed \ t = VxI = V²\R ⇒ P_w & R at constant [V]

Question 15

the electric power ( or electric energy ) consumed increases in owr houses more lamp is switched on GR

Answer 15

in our houses ; the voltage is constant 220 v and all lamps and insturment are connected in parrallel so by switching on more lamp ( adding resistance in parallel ) the total resistance decreases P_w= E.energy consumed = V X R = V²\R ⇒ P_w&1\R at constant (V)
