Find power consumed by each element 4 find power consumed by

(4) find power consumed by each element.

Solution

we have given to find power consumed

we will be using formula

Power= voltage(V)*current(I)

Element-1:

V=50v

I=-(7+3)=-10A (because current is leaving positive terminal)

so, power = V*I=50*-10

power=-500 watt.......ANswer

Element-2:

V=10v

I=3=3A

so, power = 10*3=30

power=30 watt.......ANswer

Element-3:

V=10v

I=7=7A

so, power = V*I=10*7

power=70 watt.......ANswer

Element-4:

V=30v

I=1=1A

so, power = V*I=30*1

power=30 watt.......ANswer

Element-5:

V=30v

I=5=5A

so, power = V*I=30*5

power=150 watt.......ANswer

Element-6:

V=30v

I=-(-4)=4A (because current is leaving positive terminal)

so, power = V*I=30*4

power=120 watt.......ANswer

Element-7:

V=10v

I=(5+1)=6A

so, power =V*I=10*6

power=60 watt.......ANswer
