How Do You Calculate Energy Transfer in a Circuit Component?

AI Thread Summary
To calculate energy transfer in a circuit component, use the formula: Energy (E) = Power (P) x Time (t). Power can be calculated using the formula: P = Voltage (V) x Current (I), which in this case is 12V x 2A, resulting in 24W. Over a period of 1200 seconds, the energy transfer would be E = 24W x 1200s, equaling 28,800 Joules. Understanding the relationship between power and energy is crucial for solving such problems. Reading the textbook for further clarification on these concepts is recommended.

I am currently stuck on how to work out this question.

Calculate the energy transfer in 1200s in a component when the p.d across it is 12V and the current is 2A.

I have been attempting it for at least half hour but still no luck.

Can somebody please help me out on how to work it out :)

Do you know how to calculate the power dissipation? Do you know the relation between power and energy?
 
I have a textbook here with equations in but they are hard to type because they have the Delta triangle in them. But if you could further explain these to me that would be great.
 
If you can't tell me in words what the power dissipated in a resistor is, it sounds like you need to study more. Try reading the textbook.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
