b 303 V
To find the voltage, use the formula P = IV, where P is power (in watts), I is current (in amperes), and V is voltage (in volts).
Given:
P = 300 W
I = 3 A
Solve for V:
300 W = 3 A * V
V = 300 W / 3 A
V = 100 V
Therefore, the flatscreen television needs 100 V, which is not listed as an option. This means there may have been a mistake in the given information.
A flatscreen television uses 3 A and has a power rating of 300 W. How many volts does it need
a 900 V
b 303 V
c 297 V
d 100 V
