June 7 ...
LEDs light up when electrical current flows through them. To get current to flow through an electrical circuit, you need to apply a voltage (measured in volts (V)) from a power supply like a battery or a wall adapter (like a phone charger).However, you have to be careful because the LED will burn out if too much current flows through it. Electrical current is measured in amperes (A), …
If the temperature reaches a critical point, the battery can explode or catch fire. What temperature do lithium batteries explode? Lithium-ion batteries can explode at temperatures above 60°C (140°F).
