How much power is produced by a flashlight that has a voltage of 12 volts and a current of 6.5 × 10-2 amps?

Question

A.
0.78 watts
B.
78 watts
C.
190 watts
D.
0.0054 watts
E.
1.9 watts

Answer 1

To find the power produced by the flashlight, you can use the formula:

\[ \text{Power (P)} = \text{Voltage (V)} \times \text{Current (I)} \]

In this case, the voltage \( V \) is 12 volts and the current \( I \) is \( 6.5 \times 10^{-2} \) amps.

Now, let's calculate the power:

\[ P = 12 , \text{V} \times 6.5 \times 10^{-2} , \text{A} \]

\[ P = 12 \times 0.065 = 0.78 , \text{watts} \]

So, the power produced by the flashlight is:

A. 0.78 watts
