Do capacitors in series increase voltage?
Do capacitors in series increase voltage? Capacitors connected in series will have a lower total capacitance than any single one in the circuit. This series circuit offers a higher total voltage rating. The voltage drop across each capacitor adds up to the total applied voltage. This is why series capacitors are generally avoided in power […]

What is the main energy transfer that takes place in a loudspeaker?
What is the main energy transfer that takes place in a loudspeaker? Whereas a microphone converts the movements of its diaphram due to sound energy into electrical signals, loudspeakers convert electrical energy into motion of the diaphram and thus into sound energy. What form of energy is the fan blades spinning? A fan converts mechanical […]

How do we use total internal reflection?
How do we use total internal reflection? Applications of total internal reflection (TIR) fibre broadband internet sends computer information coded as pulses of light along underground optical fibres; doctors can look at the inside of their patients using an endoscope – a long tube which guides light into the patient and then guides the reflected […]

What was the world called before it split up?
What was the world called before it split up? Pangea Why was Pangea so hot? Monsoon climate on Pangea In the Northern Hemisphere summer, when the earth’s axial tilt was directed toward the sun, Laurasia would have received the most direct solar insolation. This would have yielded a broad area of warm, rising air and […]
What is the most aggressive color?
