Answer:
The impedance of the inductor is ω L:
This is in parallel wth R giving a resistance of the parallel combination:
1 / Rp = 1 / ω L + 1 / R
Rp = (ω L * R) / (ω L + R) for the impedance of the parallel combination
Total resistance (impedance) Rt = Rp + R2 = Z
One can use the term impedance to show that the resulting current is not in phase with the resulting voltage
phase angle φ - cos φ = ω L / Rt
V = I Z shows the relation of voltage and urrent
Answer:
Resistance
Explanation:
The energy is changed into light and heat energy in the case of light bulbs providing resistance. In the case of the toaster, it changes the electricity into heat, causing resistance.
Answer:
20 seconds
Explanation:
The equation for Power is:

Which means...

We can plug in the given values into the equation:


Answer:
aerodynamics
Explanation:
if an object like a car is going 200 mph at max speed and then the car gets aerodynamic or smoothed to the point that air can get by the car it could end up going another 20 mph faster
Answer:
False
Explanation:
<em>If one of the bulbs is removed from the series, the other bulb will not come on at all.</em>
This is because the removal of one of the bulbs would interrupt the flow of current though the entire circuit.
Hence, that the other one will get brighter if one of two bulbs in a circuit is removed from its socket is not true.
