With 0.45 amp flowing through an 18-ohm resistor, the voltage across it is
V = I R = (0.45) x (18) = <em>8.1 volts .</em>
"But I asked for the battery voltage! That's the voltage across the resistor."
The ends of the resistor are connected directly to the battery terminals.
They're the same voltage.
"But what about the 6-ohm resistor ? Where does that figure in ?"
In parallel, it doesn't. It's also connected directly across the battery,
and it has its own current.
In parallel, neither resistor knows or cares whether or not there are
any other resistors present. In parallel, it makes no dif.
Answer:
direct current hope this helped : )
For the answer to the question above, i<span>n </span>direct current<span> (</span>DC<span>), the </span>electric charge<span> (</span>current)only flows<span> in one direction. </span>Electric charge<span> in alternating </span>current<span> (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the </span>current<span> changes direction. So my answer is A.</span>
Answer:
The moment of inertia is 
Explanation:
The moment of inertia is equal:
If r is 
and 
Answer:
Im pretty sure it's C
Explanation:
The answer A talks about constant speed, which does not correspond to Net Force. The answer B, talks about constant velocity, but talks about how much force apposes the box. The answer C talks about the value of the net force acting on the box, so im pretty sure the answer is C.
