of solar radiation is 1000 W/m2. However, your solar cells only have an efficiency of 11% (that is, only 11% of the sunlight power transmitted to the solar cells is delivered to the rechargeable battery). While the circuit is connected, you measure at one instant the potential difference across the battery to be 4.90 V and the current in the circuit to be 0.25 A. What is the area of the array of solar cells? _____________ m2

A solar panel measures 80 cm x 50 cm. In direct sunlight, the panel delivers 3.2 A at 15 V. If the intensity of sunlight is 1 000 W/m2, what is the efficiency of the solar panel in converting solar energy into electrical energy?
The 20-W LED bulb can provide the same amount of light output as the 100-W incandescent light bulb. How much percentage you could save for using the LED bulb in place of the incandescent bulb for one year, assuming ₱7.50 per kilowatt-hour is the average energy rate charged by the power company? Assume that the bulb is turned on for 7 hours a day. a.) 20% b.) 80% c.) 150% d.) none of the above
you are standing 2.5 m from a 150-W lightbulb. If the pupil of your eye is a circle 5.0 mm diameter, how much energy enters your eye per second? (assume 5.0% of the lightbulb's power is converted to light)
An incandescent lightbulb is an inexpensive but highly inefficient device that converts electrical energy into light. It converts about 10 percent of the electrical energy it consumes into light while converting the remaining 90 percent into heat. The glass bulb of the lamp heats up very quickly as a result of absorbing all that heat and dissipating it to the surroundings by convection and radiation. Consider an 8-cm-diameter 60-W lightbulb in a room at 25°C. The emissivity of the glass is 0.9. Assuming that 10 percent of the energy passes through the glass bulb as light with negligible absorption and the rest of the energy is absorbed and dissipated by the bulb itself by natural convection and radiation, determine the equilibrium temperature of the glass bulb. Assume the interior surfaces of the room to be at room temperature.
A 9 W led lightbulb emits the same light as a 60 W standard lightbulb. If a power company charges 10 cents per kW.h, then how much money do you save by using the led lightbulb instead of the standard lightbulb for 30 days?
Suppose a battery operates a 2.25 W electric clock for 19.5 months. 1. What is the available energy content, in joules, of the battery? 2. How many years can a battery that supplies 7.75 × 104 J run a pocket calculator that consumes energy at the rate of 1.05 × 10-3 W?
Why is the following situation impossible? A politician is decrying wasteful uses of energy and decides to focus on energy used to operate plug-in electric clocks in the United States. While many people use their smartphone as an alarm clock, he estimates that there are still 270 million plug-in alarm clocks in continuous use. The clocks transform energy taken in by electrical transmission at the average rate 2.50 W. The politician gives a speech in which he complains that, at today’s electrical rates, the nation is losing $100 million every year to operate these clocks.
An 11.6 W energy efficient fluorescent light bulb is designed to produce the same illumination as a 42.8 W incandescent light bulb. How much energy does the fluorescent bulb use if it is turned on for 10 hours? Answer in units of Joules. Answer to the one's place.
An 80 kg astronaut has gone outside his space capsule to do some repair work. Unfortunately, he forgot to lock his safety tether in place , and he has drifted 5.0 m away from the capsule . Fortunately, he has a 1000 W portable laser with fresh batteries that will operate it for 1.0 h. His only chance is to accelerate him self toward the space capsule by firing the laser in the opposite direction. He has a 10-h supply of oxygen. How long will it take him to reach safety ?
