CucuitThis charge deposited on 4uf Capacitor the circuitis+12 V2 uf6 ufD 6X 10-6c3 24 x 10-6-c2) 12 x 10-6ca) 25 x 10-6c |
|
Answer» Explanation: As the capacitors 4μF and 2μF are connected in parallel and are in SERIES with 6μF capacitor, their EQUIVALENT capacitance is (2+4)×62+4+6=3μF Charge in the circuit, Q=3μF×12V=36μC image Since, the capacitors 4μF and 2μF are connected in parallel, THEREFORE potential difference across them is same. ⇒Q1Q2=C1C2=42 or Q1=2Q2 Also, Q=Q1+Q2 ∴36μC=2Q2+Q2 or Q2=36μC3=12μC Q1=Q−Q2=36μC−12μC =24μC=24×10−6C |

Light energy25 JElectrical energyinto lamp40 JHeat energy40 Ja) His diagram shows more energy in the output than in the input. What two false statements does thisdiagram show?(6) Energy is being destroyed(iii) Energy is conserved(ii) Energy is being created(iv) Energy is not conserved |
|
Answer» Answer: Light energy is a kind of kinetic energy capable of allowing VARIOUS forms of lights visible to the human eyes. Light is known as a type of electromagnetic radiation produced by hot OBJECTS such as lasers, bulbs and sunlight. Electrical energy is the power an atom's charged particles have to CAUSE an action or move an object. The movement of electrons from one atom to another is what results in electrical energy. Every time you plug a TOASTER or cellphone charger into a wall outlet, electrical energy is POWERING those devices. |
