In 2011, a Welsh club participated in the Premier League for the first time after Swansea City gained promotion. The first Premier League match to be played outside England was Swansea City's home match at the Liberty Stadium against Wigan Athletic on 20 August 2011. In 201213, Swansea qualified for the Europa League by winning the League Cup. The number of Welsh clubs in the Premier League increased to two for the first time in 201314, as Cardiff City gained promotion, but Cardiff City was relegated after its maiden season.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Did Swansea qualify for the Europa Leaque in 2012-13?
Ah, so.. In 201213, Swansea qualified for the Europa League

The currentvoltage characteristic of an LED is similar to other diodes, in that the current is dependent exponentially on the voltage (see Shockley diode equation). This means that a small change in voltage can cause a large change in current. If the applied voltage exceeds the LED's forward voltage drop by a small amount, the current rating may be exceeded by a large amount, potentially damaging or destroying the LED. The typical solution is to use constant-current power supplies to keep the current below the LED's maximum current rating. Since most common power sources (batteries, mains) are constant-voltage sources, most LED fixtures must include a power converter, at least a current-limiting resistor. However, the high resistance of three-volt coin cells combined with the high differential resistance of nitride-based LEDs makes it possible to power such an LED from such a coin cell without an external resistor.

Ah, so.. the current is dependent exponentially on the voltage

The cloth or fiber material used, resin material, and the cloth to resin ratio determine the laminate's type designation (FR-4, CEM-1, G-10, etc.) and therefore the characteristics of the laminate produced. Important characteristics are the level to which the laminate is fire retardant, the dielectric constant (er), the loss factor (t), the tensile strength, the shear strength, the glass transition temperature (Tg), and the Z-axis expansion coefficient (how much the thickness changes with temperature).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What element of a laminate is designated by the cloth to resin ratio, among other things?
Ah, so..
type designation
