(a) A battery delivers 5A for 0.5 second when the medical instrument is switch on. Determine the number of electrons flow out of the battery in that period. (b) The resistance of a circular copper wire is 0.352. If the radius of the wire is 4mm. What is the length of this wire? (c) The current flowing through a 2.3MS2 resistor is 52.6µA. Determine the voltage across the resistor and the power it is dissipating (d) A refrigerator of rating 600W, 200V and an electric fan of rating 120W, 200V are connected in series to a 200V supply. What is the total power dissipated in the circuit? (a) A battery delivers 5A for 0.5 second when the medical instrument is switch on.
