Concept explainers

Ohm's law

Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.

Path of Least Resistance

In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.

As shown in Figure CQ33.6, a person pulls a vacuum cleaner at speed v across a horizontal floor, exerting on it a force of magnitude F directed upward at an angle with the horizontal.

Which of the following statements are true about electric power and electric potential energy? List all that apply. Power is the amount of energy used by an electrical appliance. Power is the rate at which energy is used by an electric circuit. A kiloWatt•hour is a unit of electric power. A Joule/second is a unit of power. A 60-Watt light bulb would consume 30 Joules of electrical energy in 2 seconds. A 120-Watt light bulb would consume 1200 Joules of electrical energy in 6 seconds. A charge moving through an electric circuit would gain electric potential energy in the internal circuit and lose electric potential energy in the external circuit. Charge has the greatest amount of electric potential energy at the - terminal of the battery. If a 60-Watt light bulb is placed in a 120-Volt circuit, then the current in the light bulb is 2 Amps. Consider two light bulbs with different power ratings. A 60-Watt light bulb has a greater resistance than a 100-Watt light bulb.

A modern LED light bulb that emits as much visible light as a 40.0-W incandescent only draws 4.50 W of power. How much does it cost to operate this bulb for 24 hours? c. A particular electric oven requires a potential difference of 220 V and draws of 22.0 A of current when operating. How much does it cost to operate the oven for 4.30 hours?

Cost of Electricity A refrigerator is an appliance that is left running all the time. In New Orleans, Louisiana, the average residential electricity rate charged by Entergy is 9.82¢/kWh. Using this rate, how much will it cost to operate a refrigerator that requires 220 Watts in one month. You can use the following steps: 1. Convert power to kW = 2. Time (in hours) in one month (30 days) = %3D 3. Energy consumption (Power x Time) = 4. Cost (Rate x Energy) in dollars =
Compare the energy consumption of two commonly used items in the household. Calculate the energy used by a 1.00 kW toaster oven, Wtoaster, which is used for 5.80 minutes, and then calculate the amount of energy that an 11.0 W compact fluorescent light (CFL) bulb, Wlight, uses when left on for 10.50 hours. Wtoaster = kWh Wlight = kWh
Part (b): Watts, volts, and ohms are SI units that can be expressed in the 'base' SI units as follows: kg-m² 53 ohm = kg-m² $³.A21 watt = volt= bottle cm kg.m² $3.A' (Recall that 'A' is the abbreviation for an ampere.) Use algebra and the equation at the top of the page (P=V²/R) to show that the base SI units for watts equal the base SI units for volts²/ohms. You do not need any numbers in this algebraic exercise. Instead, treat each of the base SI units (kg, m, s, A) as if it were an algebra variable (like x or y). Start with the following equation and substitute the base SI units for watt, volt, and ohm: watt = volt² ohm
