A 10.0 V battery is connected to a 120-ohm resistor. Ignoring the internal resistance of the battery
Calculate the power delivered to the resistor.​

Respuesta :

Answer:0.83 watts

Explanation:

Voltage=10v

Resistance=120ohm

power=(voltage)^2 ➗ resistance

Power=10^2 ➗ 120

Power=(10x10) ➗ 120

Power=100 ➗ 120

Power=0.83watts

The power delivered to the 120 ohm resistor will be "0.93 watts".

Resistance and Power

According to the question,

Voltage, V = 10 V

Resistance, R = 120 ohm

We know the relation,

→ Power = [tex]\frac{(Voltage)^2}{Resistance}[/tex]

or,

→ P = [tex]\frac{V^2}{R}[/tex]

By substituting the values, we get

     = [tex]\frac{(10)^2}{120}[/tex]

     = [tex]\frac{10\times 10}{120}[/tex]

     = [tex]\frac{100}{120}[/tex]

     = 0.93 watts

Thus the above answer is appropriate.
