To calculate the power usage of a headlamp, you can use the formula:
\[
\text{Power (Watts)} = \text{Voltage (Volts)} \times \text{Current (Amperes)}
\]
In your case, the headlamp operates at 12 volts and uses 3.75 amps of current. Plugging in those values:
\[
\text{Power} = 12 \, \text{V} \times 3.75 \, \text{A} = 45 \, \text{W}
\]
So, the power usage of the 12-volt headlamp is 45 watts.
