An MP3 player operates with a voltage of 3.7 V, and is using 0.14 W of power. Find the current being supplied by the player's battery.
P= (I)(V) so...
I= (P)/(V)= (0.14W)/(3.7V)
To find the current being supplied by the player's battery, we can use the formula:
Power (P) = Voltage (V) × Current (I)
In this case, we know the power (0.14 W) and the voltage (3.7 V), so we can rearrange the formula to solve for the current (I):
I = P / V
Plugging in the given values, we have:
I = 0.14 W / 3.7 V
Calculating this, we find:
I ≈ 0.0378 A (or 37.8 mA)
Therefore, the current being supplied by the player's battery is approximately 0.0378 Amperes (or 37.8 milliamperes).
To find the current being supplied by the MP3 player's battery, we can use the formula:
Power (P) = Voltage (V) × Current (I)
Given that the voltage (V) is 3.7 V and the power (P) is 0.14 W, we can rearrange the formula to solve for the current (I):
I = P / V
Plugging in the given values, we get:
I = 0.14 W / 3.7 V
Now we can calculate the value:
I ≈ 0.0378 A
Therefore, the current being supplied by the MP3 player's battery is approximately 0.0378 Amperes.
