Answer:
- The investment is P = $32550
- Interest rate is r = 2% or 0.02
- Time is t = 5 years or t = 10 years
Formula to use:
- A = P(1 + r)^t
For t = 5 we get:
- A = 32550*(1 + 0.02)^5 = $35937.83
For t = 10 we get:
- A = 32550*(1 + 0.02)^10 = $39678.27
Step-by-step explanation:
Answer :-
β Current in 10 Ξ© resistor = 4 A
β Current in 20 Ξ© resistor = 2 A
β Power of the 10 Ξ© resistor = 160 W
β Power of the 20 Ξ© resistor = 80 W
Explanation :-
We have :-
β 1st resistance (Rβ) = 10 Ξ©
β 2nd resistance (Rβ) = 20 Ξ©
β Total current (I) = 6 A
______________________________
The current in the 10 Ξ© resistor is :-
Iβ = (Rβ/Rβ + Rβ) Γ I
β Iβ = (20/10 + 20) Γ 6
β Iβ = 20/30 Γ 6
β Iβ = 4 A
The current in the 20 Ξ© resistor :-
Iβ = (Rβ/Rβ + Rβ) Γ I
β Iβ = (10/10 + 20) Γ 6
β Iβ = 10/30 Γ 6
β Iβ = 2 A
______________________________
Power of 10 Ξ© resistor :-
Pβ = IΒ²β Γ Rβ
β Pβ = (4)Β² Γ 10
β Pβ = 16 Γ 10
β Pβ = 160 W
Power of 20 Ξ© resistor :-
Pβ = IΒ²β Γ Rβ
β Pβ = (2)Β² Γ 20
β Pβ = 4 Γ 20
β Pβ = 80 W
