can get help with these questions?  The graph below shows the characteristic electric curves for the conductors K and L 

1. The resistance of K and are RE and RL. Calculate RE and RL.

2. Explain whether the conductors K and L are Ohmic or not.

The two conductors are now connected in series to a single battery with negligible internal resistance. The total power dissipated in the circuit is 75 W.

3. Show that the potential difference of the battery is 12 V.

4. The conductors are now connected to the same power supply but in parallel with one another. State whether the power dissipated in the circuit will be larger, same or smaller than 75 VW, and explain why.​
