The IdeaPad S10 was Lenovo's first netbook. [4] While Engadget found the design unremarkable, the low starting price was well-received. [4] The S10 featured a 10.2-inch (260 mm) TFT active matrix 1024×576 or 1024×600 display with an 80 or 160 GB hard disk drive and 512 MB or 1 GB DDR2 Random Access Memory, both of which could be upgraded via a trap door on the bottom of the netbook.
The rating of a brushless motor is the ratio of the motor's unloaded rotational speed (measured in RPM) to the peak (not RMS) voltage on the wires connected to the coils (the back EMF). For example, an unloaded motor of K v {\displaystyle K_{\text{v}}} = 5,700 rpm/V supplied with 11.1 V will run at a nominal speed of 63,270 rpm (= 5,700 rpm/V ...
This battery, introduced in 1901, was very common in continental Europe until the 1970s. It usually contains three B cells in series. In Switzerland as of 2008, 4.5-volt batteries account for only 1% of primary battery sales. [89] PP3, 9-volt, or E [90] Radio battery Smoke alarm battery Square battery Transistor battery 006P MN1604

The first laptops in the IdeaPad Y Series line were showcased in CES 2008. [1] These were the IdeaPad Y710 and Y510 laptops, with 17-inch and 15-inch screens, respectively. [13] The Y series is a line of ordinary laptops with gaming-oriented appearance – a marked difference from ThinkPads. [3]
A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
The volt-ampere (SI symbol: VA, [1] sometimes V⋅A or V A) is the unit of measurement for apparent power in an electrical circuit. It is the product of the root mean square voltage (in volts) and the root mean square current (in amperes). [2] Volt-amperes are usually used for analyzing alternating current (AC) circuits.
The current–voltage characteristics of four devices: a resistor with large resistance, a resistor with small resistance, a P–N junction diode, and a battery with nonzero internal resistance. The horizontal axis represents the voltage drop, the vertical axis the current. All four plots use the passive sign convention.
