Answer:
Current remains constant
Explanation:
From Ohm's law we know that V=IR where V is voltage across the circuit, I is the current across circuit and R is resistance. Making I the subject of the formula then
When voltage and resistance are doubled then voltage will be 2V while resistance 2R hence
A option will be the answer.
Time = (distance) / (speed)
Time = (150 x 10⁹ m) / (3 x 10⁸ m/s) =
50 x 10¹ sec =
<em>500 sec</em> = 8 min 20 sec
