Define electrical power.Lus An electric heating coil of resistance R is immersed in 1 kg of water at 20 °C. The coil is connected in series with a resistor Y across a 240 V mains supply. The temperature of the water rises to the boiling point in 10 minutes. When Y is disconnected, the time taken for the 1 kg of water at the same temperature to boil is reduced to 6 minutes. Neglecting all heat losses, calculate the resistance R, of Y. | Specific heat capacity of water = 4200 J kg' K"] [7 ma State and exnlain th

A DC circuit is shown in th figure below. (a) What is the current through 1.00 ohm? 2.00 ohm resistor? (b) What is the voltage on the 4.00 ohm? on the 6.00 ohm resistor? (c) What is the power dissipated on the 3.00 ohm resistor?

In (Figure 1), the total resistance is 12.0 kΩ , and the battery's emf is 26.0 V . The time constant is measured to be 14.0 μs . Calculate the total capacitance of the circuit. Calculate the time it takes for the voltage across the capacitor to reach 15.0 VV after the switch is closed.

A 72.3 ohm resistor is put into a circuit with a 13 volt battery. What is the power dissipated (in watts) by the resistor?

One wire in a high-voltage transmission line carries 1 000 A starting at 560 kV for a distance of 270 mi. If the resistance in the wire is 0.500 n/mi, what is the power loss due to the resistance of the wire? MW

A 802.73 watt generator can produce a current of 17.12 amps through a circuit.  What is the total voltage across the circuit?

The cost of electricity varies widely throughout the United States; $0.120/kWh is a typical value. At this unit price, calculate the cost of the following. (a) Leaving a 80.0-W porch light on for 2 weeks while you are on vacation. $ 3.23 (b) Making a piece of dark toast in 3.00 min with a 860-W toaster. 0.00516 X Your response is off by a multiple of ten. (c) Drying a load of clothes in 40.0 min in a 5,800 W dryer. 0.464 X Your response is off by a multiple of ten.
