Final answer:
The total power dissipated by a 100-ohm resistor with 100 volts across it is 100 watts.
Step-by-step explanation:
The total power dissipated by a resistor in a circuit can be calculated using the formula P = V^2 / R, where P is the power in watts, V is the voltage across the resistor in volts, and R is the resistance value in ohms. For a resistor with a value of 100 ohms and a circuit voltage of 100 volts, the total power dissipated by the resistor is given by:
P = (100 V)^2 / 100 Ω = 10,000 V^2 / 100 Ω = 100 W.
So, the resistor dissipates 100 watts of power.
