Answer :
Final answer:
To calculate the current drawn by a portable radio transmitter with an input power of 6 W from a 3.7 V battery, use the formula I = P/V, resulting in a current of 1.62 A.
Explanation:
The question involves calculating the current drawn from a 3.7 V battery by a portable radio transmitter with an input power of 6 W. To find the current, we use the power formula P = IV, where P is power in watts, I is current in amperes, and V is voltage in volts. Rearranging the formula to solve for I, we get I = P/V.
Given that the input power P is 6 W and the voltage V is 3.7 V, we can substitute these values into the formula to find the current. Therefore, the current I is I = 6 W / 3.7 V = 1.62 A. Hence, the radio transmitter draws a current of 1.62 A from the 3.7 V battery.
