You have several electrical units listed there:
a). C often used to represent a Capacitance.
b). 'A' often represents 'Ampere', the unit of Current.
c). 'R' often used to represent a Resistance.
d). 'E' often used to represent a Voltage (Electromotive Force).
Not to mention ' A. C ', a whimsical offering,
reminiscent of 'Alternating Current'.
Answer:
Slip Rings
Explanation:
The wound rotor motor has a three-phase winding with each one connected to seperate slip rings. These slip rings contain brushes which form a secondary circuit where resistance can be inserted and this will allow for the rotor current to run more in phase with the stator current which will result in increased torque that is created
A solar panel are most efficient under natural sunlight, however, a solar panel can work using artificial light simply because a solar panel collects photons which collide with silicon atoms transferring their energy which cause them to lose electrons.
Answer:
The conditions necessary for hearing the echo. The distance between the sound source and the reflecting surface must not be less than 17 metres where the time period between hearing the original sound and its echo should not be less than 0.1 of a second.
Answer:
Landed before it explodes
Explanation:
vf = vi + at,
0 = 145 - (9.8)t,
t = 14.79 s (Time to reach highest point)
14.79 x 2 = 29.59 s (Time to land on the ground)
It will have landed before it explodes because both the time to reach the highest point and the time to land on the ground are less than 32 seconds.
