    OCR-B unit 6 specimen question help!? :confused:

    camera has a 4.1V battery which lasts for 2 hours of continuous use of the camera. The capacity of the battery (total charge avaliable) is 1400mA hours. It takes 7 hours for a charging unit to recharge the battery...
    i) express the capacity of the battery in coulombs
    ii) show that the average current in the camera during continuous use is 0.7A
    iii) Calculate the power consumption of the camera in continuous use.
Do you agree with the proposed ban on plastic straws and cotton buds?
