Energy of capacitor

We want to store sufficient energy in a .01-F capacitor to supply 5-hp for 1 hour. To what voltage must the capacitor be charged? (1 hp=745.7 watts). Does this seem to be a practical method for storing this amount of energy? Do you think that an electric automobile based on capacitive energy storage is feasible?

Calculate the power delivered to each resistor

Calculate the power delivered to each resistor in the attached .jpg. Please show all work. Thanks.

Resistors

Three resistors of resistance 2,4,10 ohm respectively are connected a) in series with a 12V supply b) in parallel across a 12V supply 1) In each case draw a circuit diagram and determine the current through each resistor and the potential drop across each resistor 2) Determine the power dissipated in the 10 ohm resistor in both case (a) and case (b) 3) For each of (a) and (b) determine the energy provided per minute by the supply

Power/current required

An X-ray machine operates from a 220V supply. The machine power is 800W and the supply must also supply six 24W, 220V indicator lights. Please answer all questions with full explanations thankyou 1) What is the total power required? 2) What is the current drawn from the 220V supply? 3) A transformer with 250 turns in its primary is used to obtain the X-ray tube voltage of 40 kV, how many turns should there be in the secondary winding? 4) What is the current in the secondary coil? 5) Draw a circuit diagram showing the transformer and the supplies to the machine and indicator lights.
