For this case we have, by definition, that:
Resistance is a component that is responsible for limiting the amount of current that can pass through a circuit, converting excess heat.
Consume energy.
Option A represents a swicth, option B represents a luminaire and option D represents a voltage source.
So, the correct option is C,
Answer:
Option C
Answer:
Jupiter's gravitational acceleration is 24.8 m/s^2
Explanation:
Recall that the weight under the influence of a gravitational acceleration G is defined as:
Weight = m * G
Then, in our case we have
372 N = 15 kg * G
G = 372/15 m/s^2
G = 24.8 m/s^2
The rock will sink because it is more dense than water.
Resistance-1 = (voltage-1) / (current-1) =
(12 V) / (0.185 A) = 64.9 ohms .
Resistance-2 = (voltage-2) / (current-2) =
(90 V ) / (1.25 A) = 72 ohms .
The resistance changed between situation-1 and situation-2 .
How did that happen ?
Power = (voltage) x (current)
Power-1 = (12) x (0.185) = 2.22 watts
Power-2 = (90) x (1.25) = 112.5 watts
The poor resistor dissipated 51 times as much power during
the second trial. It got all heated up, and its resistance went
through the roof.
Carbon resistors behave nicely and reliably, until you try to
toast bread or light up your bedroom with them.
I think that would be c) mirror because mirrors reflects light and can't create it.
