Answer:
V = W = 12 J/C * 150 C = 1800 J work in moving 150 C of charge
P = W / t = 1800 J / 60 s = 30 watts
Answer:
30 Watts
Explanation:
We're provided with the following information:
- Amount of Charge flown (Q) = 150 C
- Potential Difference (V) = 12 V
- Time (T) = 1 min
= 60 seconds
Current:
Current is the rate of flow of charge ,i. e., The amount of charge flowing "per second":
[tex]\boxed{\mathfrak{Current(I)=\frac{Charge(Q)}{Time(T)} }}[/tex]
We have:
- Charge flown (Q) = 150 C
- Time (T) = 60 seconds
Finding the current flown using the above mentioned formula:
[tex]\implies \mathsf{I=\frac{150}{60} }[/tex]
[tex]\implies \mathsf{I=\frac{5}{2} }[/tex]
=> I = 2.5 A
A(Amperes) is the SI unit of Current
Relation between Power, Voltage and Current:
We've a relation between Power, Current and Voltage, derived with the help of "Joule's Law of Heating", and that is:
[tex]\boxed{\mathfrak{Power(P)=Voltage(V) \times Current(I)}}[/tex]
We can finally find Power, Since we have:
- Current (I) = 2.5 A
- Voltage (V) = 12 V
=> P = 12 × 2.5
=> P = 30 W
W, Watts, is the Si unit of Power
