    Answer:

    1.3875 Joules. 2. 0.17A 3. 35.47volts

    Explanation:

    1. Energy = Q × V = 5 × 775 = 3875 Joules.

    Q is quantity of electricity in Columbs

    V is Voltage in volts

    2. From Q = I × t

    Q is quantity of electricity in Columbs

    T is time taken

    I is current

    Now we define I as the quantity of electricity in 1 sec; hence;

    200= I × 20× 60 [ 20minutes converted to seconds ]

    I = 200/ 20× 60.= 200/1200=0.1667

    = 0.17A( to the nearest hundredth)

    3.v = E/ Q ( from equation in question 1)

    V = 337/9.5 = 35.47volts
