To find the voltage required by the television, you can use the formula derived from Ohm's Law:
\[ \text{Power (Watts)} = \text{Voltage (Volts)} \times \text{Current (Amps)} \]
Rearranging the formula to find voltage gives us:
\[ \text{Voltage (Volts)} = \frac{\text{Power (Watts)}}{\text{Current (Amps)}} \]
Plugging in the values:
\[ \text{Voltage} = \frac{300 \text{ Watts}}{3 \text{ Amps}} = 100 \text{ Volts} \]
So, the flat-screen television needs **100 volts**.
\[ \text{Power (Watts)} = \text{Voltage (Volts)} \times \text{Current (Amps)} \]
