Car headlights have both low beams and high beams. the high beams may be necessary when it is very dark outside. if the power for the high beam is 60.0 watts and the current is 5.0 amps, how much voltage is required?

Answer : Voltage, V = 12 V.

Explanation :

It is given that,

The power for the high beam is, P = 60.0 watts

Current flowing, I = 5 A

Car headlights have both low beams and high beams. The high beams may be necessary when it is very dark outside.

We know that the power of any source is given by :

So, the voltage required for the high beam is 12 V.

i dont have a visual in front of me, but i can you reason to try to get the right one. the graph should look like this, 0 to 6 there is a spike, 12 to 14 there should be a very low point. slight increase in the graph at 12 to 14, and flat 14 to 18
