If the circuit in the motorcycle runs off a standard 12 V battery, and one of the headlights is switched on, current flowing through the headlight is measured at 3.75 A. What is the power usage of the headlamp? Report the answer to two significant digits

P = 45 Watt

Explanation:

The electrical power used by an electrical device or the electrical circuit is given by the following formulae:

P = VI

P = I²R

P = V²/R

where,

P = Electrical Power Consumed by the Device

V = The Voltage applied to the circuit or device

R = Resistance of device or circuit

I = Current passing through the device or circuit

We have the following data for our circuit:

V = 12 volts

I = 3.75 A

Therefore, it is clear from the data that we will use the first formula:

P = VI

P = (12 volts)(3.75 A)

P = 45 Watt

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
