A

lightbulb designed to work at 240 V in England is instead connected to a 120 V source. Discuss the changes in the bulb's rms current and power when it is at 120 V compared with a 240 V . Assume the bulb is ohmic. A 25 ohm resistor is wired directly across a

ac source. What happens to the timeaverage power, rms voltage, and rms current when the reistor's value changes to 500 ? A 25 ohm resistor is wired directly across a

ac source. What happens to the timeaverage power, rms voltage, and rms current when the ac source is changed to 240 V ?
