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.
