Final answer:
The power consumed by a 25 ohm resistor connected to a 240V source is calculated using the formula P = V^2 / R, resulting in 2304 watts or 2.304 kilowatts.
Step-by-step explanation:
To calculate the power consumed by a resistor, we can use the formula P = V2 / R, where P is the power in watts, V is the voltage in volts, and R is the resistance in ohms. In this case, we have a 240V source connected to a 25 ohm resistor. Plugging these values into the formula, we get P = (240V)2 / 25Ω, which equals 2304 watts or 2.304 kilowatts.
otherwise ,To calculate the power used by a 240V source connected to a 25-ohm resistor, we can use the formula P = V^2 / R, where P is the power, V is the voltage, and R is the resistance. Plugging in the values, we get P = (240V)^2 / 25 ohm = 921.6W.
Therefore, the power used is 921.6 watts.
