A static electrical device has 2000 turns uses 4000 mA from the supply connected to a laptop whichhas a power of 20 V, 1000 W. How can you find the amount of current used by the laptop? Identify suchstatic electrical device used and evaluate supply voltage taken by it. Which category does it belong basedon its ability to change voltage? Practical efficiency of such electrical device is less than 100 %. Justifywith reasons. What are possible ways to improve its efficiency?
In a simple electric circuit, Ohm's law states that V = IR, where V is the voltage in volts, I is the current in amperes, and R is the resistance in ohms. Assume that, as the battery wears out, the voltage decreases at 0.04 volts per second and, as the resistor heats up, the resistance is increasing at 0.02 ohms per second. When the resistance is 300 ohms and the current is 0.01 amperes, at what rate is the current changing? amperes per second
A 17 kA lightning bolt strikes an object for 15 μs. a. How much charge is deposited on the object? b. How many electrons is this? (For comparison, there are approximately 1028 electrons in the human body.) C. If the lightning strike discharges across a voltage potential of 250 million volts, what is the lightning bolt's power? Express your answer in the units of gigawatts (GW). d. How much energy is imparted by the lightning strike? e. A typical cell phone battery has a charged capacity of 1800 mAh at 3.7 V. If the energy from the lightning strike were harnessed, how many cell phone batteries could be fully charged using this energy? Note: It is common to use an ampere-hour (Ah) or milliampere-hour (mAh) as a measure of charge storage capacity. One mAh is the charge delivered by a one milliamp current for one hour. Without a stated voltage, however, this doesn't tell us how much energy a battery can store. For this, energy storage is typically rated in watt-hours (Wh); a smartphone…
Figure P1.27 shows an ammeter (AM) and voltmeter (VM) connected to measure thecurrent and voltage, respectively, for circuit element A. When current actually enters the + terminalof the ammeter, the reading is positive, and when current leaves the + terminalreading is negative. If the actual voltage polarity is positive at the + terminal of the VM, thereading is positive; otherwise, it is negative. (Actually, for the connection shown, the ammeterreads the sum of the current in element A and the very small current taken by the voltmeter. Forpurposes of this problem, assume that the current taken by the voltmeter is negligible.) Find thepower for element A and state whether energy is being delivered to element A or taken from it if a. the ammeter reading is +2 A and the voltmeter reading is +30 V.b. the ammeter reading is -2 A and the voltmeter reading is - 30 V.c. the ammeter reading is -2 A and the voltmeter reading is + 30 V.
