What is the power dissipated in a resistor with a resistance of 10 ohms and a current of 2.5 amperes?
Choices:
- 12.5 watts
- 17.5 watts
- 25 watts
- 32.5 watts
The power dissipated in a resistor with a resistance of 10 ohms and a current of 2.5 amperes is approximately 62.5 watts.
To find the power dissipated in a resistor, we can use the formula P = I^2 * R, where P is the power, I is the current, and R is the resistance.
In this case, the resistance of the resistor is 10 ohms and the current passing through it is 2.5 amperes.
Plugging in the values, we have P = (2.5)^2 * 10 = 6.25 * 10 = 62.5 watts.
Therefore, the power dissipated in the resistor is approximately 62.5 watts.
