Two 75 W (120V) light bulbs are wired in series, then the combination is connected to a 120 V power supply. How much power (in W) is dissipated by each bulb?

A capacitor is discharged in an RC circuit. The current decreases to 50% of its initial value in 1.8 seconds.What is the time constant of the circuit? A) 0.39 sB) 1.7 sC) 3.6 sD) 1.8 sE) 2.6 s

A 2 Ohm resistor and 1.171 F capacitor are connected in series to a 56 V DC voltage source (RC Circuit). What will be the current flowing through this circuit 3.43 seconds after the series is connected?

. An RC circuit with a 54.0 V power source is connected to a fluorescent lamp as shown in the ngure. The lamp L turns on when the voltage across the capacitor reaches 45.0V, which happens after 0.65 seconds after the switch is closed. If R = the capacitance C? (b) If we must switch the lamps 3 times in a second, what should be the value of capacitance? (c) What is the charge on the capacitor when the lamp just flashes in 3MQ, (a) what is the value of both the cases? ww R 54.0V
