To find the power usage of the headlamp in a motorcycle, you can use the formula for electrical power:
\[
P = V \times I
\]
where:
- \( P \) is the power in watts (W),
- \( V \) is the voltage in volts (V),
- \( I \) is the current in amperes (A).
In this case, you have:
- \( V = 12 \) volts,
- \( I = 3.75 \) amperes.
Now, substituting the values into the formula:
\[
P = 12 \, \text{V} \times 3.75 \, \text{A} = 45 \, \text{W}
\]
So, the power usage of the headlamp is **45 watts**.
\[
P = V \times I
\]
where:
- \( P \) is the power in watts (W),
- \( V \) is the voltage in volts (V),
- \( I \) is the current in amperes (A).
In this case, you have:
- \( V = 12 \) volts,
- \( I = 3.75 \) amperes.
Now, substituting the values into the formula:
\[
P = 12 \, \text{V} \times 3.75 \, \text{A} = 45 \, \text{W}
\]
So, the power usage of the headlamp is **45 watts**.
