What type of battery chemistry is most commonly used to power small/medium-sized multi-rotor drones?2 pointsNickel-metal hydrideLithium polymerAlkalineLead acid

A delivery drone is to be designed using a KV battery . Battery A uses dense Lithium Polymer to give a KV Rating = 300 rpm/volt whereas Battery B uses Lithium  Sulphur chemical and gives a KV Rating = 400 rpm/volt . Consider Power to be constantChoose the best possible optionABattery A should be usedBCombination of Battery A & B in series with a phase difference of 0 degree is better than individual batteriesCKV Rating does not affect the functioning of delivery drones significantlyDCombination of Battery A & B in series with a phase difference of 90 degrees is better than individual batteries

Which of the following answers refer to common battery types that can be found in modern portable devices? (Select 2 answers) Nickel-Iron (Ni-Fe) Lithium-ion (Li-ion) Nickel–Metal Hydride (Ni-MH) Lithium-ion Polymer (LiPo) Nickel-Cadmium (Ni-Cd)

Scientists have used common materials, including aluminum, sulfur, and salt, to create a new type of battery. Lithium-ion batteries were the most popular battery in the past, but they are becoming harder and more expensive to make due to a shortage of lithium. _____ the new battery provides many benefits: it is low-cost, it is able to resist failures and fires, and it charges faster than typical batteries do.21Mark for ReviewABCWhich choice completes the text with the most logical transition?AIn comparison,BWhat’s more,CSimilarly,DIn addition
