(a) How much power is dissipated in a short circuit of 240 -V AC through a resistance of 0.250$\Omega$ ? (b) What current flows?
Added by Emily W.
Step 1
Given: Voltage (V) = 240 V Resistance (R) = 0.250 $\Omega$ Use the formula for power (P) in a circuit: \[ P = \frac{V^2}{R} \] Substitute the given values: \[ P = \frac{240^2}{0.250} \] \[ P = \frac{57600}{0.250} \] \[ P = 230400 \text{ W} \] Show more…

(a) What is the resistance of a 220-V ac short circuit that generates a peak power of 96.8 kW? (b) What would the average power be if the voltage were $120 \mathrm{V}$ ac?
(II) A current $I = 1.80 \cos 377 t \quad ( I$ in amps, $t$ in seconds, and the "angle" is in radians) flows in a series $L R$ circuit in which $L = 3.85 \mathrm { mH }$ and $R = 1.35 \mathrm { k } \Omega .$ What is the average power dissipation?
