- An engineer fashions an 3.9-k equivalent resistor from a parallel combination of 4 equal- value resistors. What is the resistance (in kQ) of each individual resistor?An automatic irrigation system is going to be used, this system is represented by the following block diagram: The irrigation system will work optimally when the connected load (resistance) has the value such that it can receive the most power from the control circuit, otherwise it could be wasted energy or even damage the system for its operation. Optimum operation of the entire system must be guaranteed. The control circuit of the irrigation system is represented by the following electrical diagram: Donde la resistencia de carga que se conectará entre las terminales a y b debe ser una de entre las tres cargas existentes:A RC circuit is constructed with a (initially uncharged) 5.00-µF capacitor and a 5.00- ohm resistor, which are connected in series to an ideal battery with emf 60.0 V. At a certain time after the circuit is connected, it is found that heat is being produced in the resistor at a rate of 300 W. How much energy is stored in the capacitor at that time (in Joules)? O None of these 1.8x104 1.13x10-3 3.75x10-3 9x10-3
- With a 1200 W toaster, how much does it cost to make a slice of toast (cooking time = 1.5 minute)? Electricity costs 8 cents per kW.h. centsAn alternative to CFL bulbs and incandescent bulbs are light-emitting diode (LED) bulbs. A 100-W incandescent bulb can be replaced by a 16-W LED bulb.Both produce 1600 lumens of light. Assuming the cost of electricity is $0.10 per kilowatt-hour, how much does it cost to run the bulb for one year if it runs for four hours a day?
