Dont where socks or stand on carpet while working on a computer, also dont set components on carpet.
Answer:
Vd = 0.022 (V)
Explanation:
What we have as voltage drop is the difference between the voltage at source level (terminals) and the voltage at the terminal of electrical load ( in this case the toaster oven) that difference occures as consequence of the normal distributed resistance of conductor. But the voltage at the terminal of the electric load have to be measure between the two wires at the end of the circuit.
Therefore the voltage drop is = I*R = 11 (A) * 0,002 Ω = 0.022 (v)
Answer:
22510.8J
Explanation:
Given parameters:
Mass of lead = 4.68kg
Initial temperature = 25°C
Final temperature = 62°C
Unknown:
The heat needed to cause this temperature change = ?
Solution:
To solve this problem, we use the expression below:
H = m c Ф
H is the quantity of heat
m is the mass
c is the specific heat capacity
Ф is the temperature change
So;
Specific heat capacity of lead = 130J/kg°C
Insert the parameters and solve;
H = 4.68 x 130 x (62 - 25) = 22510.8J
