The powers of two light-bulbs are 60 W and 125 W when connected in parallel across a 130-V source. What is the power of the bulb that will output less power when the two light-bulbs are connected in series with the same source?
Lightbulb A is marked "40 W 120 V", and lightbulb B is marked "75 W 120 V". These labels mean that each lightbulb has its respective power delivered to it when it is connected to a constant 120-V source. (a) Find the resistance of each lightbulb. R(40 W 120 V) = Ω R(75 W 120 V) = Ω (b) During what time interval does 2.30 C pass into lightbulb A? Δt = s (d) In what time interval does 3.00...
several 60 w light bulbs are connected in parallel to a 120 v source. the circuit has a circuit breaker cb that is placed right after the battery that interrupts the current through itself whenever that current exceeds 9 A. Calculate the largest number of bulbs that can glow together.
Chapter 26, Problem 049 A 120 W lightbulb is plugged into a standard 120 V outlet. (a) How much does it cost in dollars per 31-day month to leave the light turned on continuously? Assume electrical energy costs US$ 0.08/kWh. (b) What is the resistance of the bulb? (c) What is the current in the bulb? (a) Number Units (b) Number Units (c) Number Units
A 60 W, 120 V lightbulb has a resistance of 12.7 ? when cold (20.0
A "120-watt" lightbulb uses an average power of 120 W when connected to an rms voltage of 120 V. What is the resistance of the lightbulb? What is the maximum current in the bulb? What is the maximum power used by the bulb at any given instant of time?
1. Find the resistance in ohms of a light bulb that produces 60 W of power when connected to 120 V household current. (5 pts) 2. Indicate if the statements below are true or false: (a) AC currents are changing, and the voltage is constant (b) DC currents are constant, and the voltage is constant (c) The time dependence of AC current and voltage follows a “sin” wave with frequency 60 Hz (d) When several light bulbs are arranged in...
A 15-W compact fluorescent light bulb is used in a lamp plugged into a 120-V wall socket. You can assume the lamp itself has zero resistance. Find (a) the resistance of the light bulb, (b) the maximum current through the bulb, and (c) the maximum power used by the light bulb. Also, if the frequency of the electricity is the typical household value of f = 60 Hz, what are the first two times that the current going through the...
