Which of these components is not necessary for current to flow in a series or parallel circuit?

1 answer:

8 0

Current requires only an EMF source ... like a battery, or a current already flowing ... and a conducting path ... like wire, ionized air, or something dissolved in water. A switch isn't needed unless you want a quick, easy way to STOP the current. A resistor isn't needed unless you want to be able to dissipate some energy from the current, or limit its magnitude.

When you look ahead while driving, it is best to:

vodka [1.7K]

I think its [B]
Personally i would say [B] only because If you are looking beyond the car in front of you..... then what if the car in front of you throws on breaks... you would hit them in the butt because you weren't paying attention to the car.
And majority of the time if your looking in the lanes beside you then you are most likely trying to get in that lane.

When the object is at half its amplitude from equilibrium, is the magnitude of its acceleration at half its maximum value?

Nezavi [6.7K]

We have F = kx or ma = kx where m and k are constants. Therefore, if x is halved, a must be halved too.
