Two 75.0 W (120 V) lightbulbs are wired in series, then the combination is connected to a 230 V supply. How much power is dissipated by each bulb? Answer in W.
a.When two resistors RA and RB are combined in series and connected to a battery it is observed that the ratio of the power dissipated in RA to that dissipated in RB is equal to 10. If this arrangement is dismantled and the same two resistors connected in parallel to the same battery, what is the ratio of the power dissipated in RA to that dissipated in RB in this new circuit? b.How much energy is converted by a 12...
Three 70.0-W, 130-V lightbulbs are connected across a ΔV = 130-V power source, as shown in the figure below. Find the total power delivered to the three bulbs and the potential difference across each. Assume the resistance of each bulb is constant (even though, in reality, the resistance increases markedly with current). An open circuit begins at a terminal with a wire extending horizontally rightwards until it reaches a lightbulb R1. After the light bulb, the wire splits downwards into...
