1. First question, What relationship exist between Voltage and Current? Is it a hyperbola, a straight slope, etc.. or what? Also what is the significance of the slope of this graph.

2.Second, After plotting the current and the reciprocal of the resistance, what is the slope and what does it represent? what relationship exist between Current and 1/Resistance

3. Last, In theory what current passes through a circuit having an 11-Ohm resistance connected across a 110-V line? 220-V Line?

P.S.
In the first question the Resistance or Ohms in the unit kOhms is constant with an incresing Voltage expressed in V. So is the Current in the unit of mA is it increasing or not?

In the 2nd question the Voltage is constant again is expressed in V with an decreasing resistance. So again is the Current in the unit of mA is it increasing or not?

The Definiton of Ohms law states: The electic field is directly proportional to the Current densicty in a circuit.
This boils down to a circuit equation which is ; E= I x R.
Wher e E is the electromotive force measured as volts.
I is the power of the circuit.Measured as amperes.
R is resistance of the electromotive force in the Circuit, and is measured in Units of inverse velocity.
Hence the Current is circuit powerr which is equal to force time velocity.

You can solve any of the components of the equation if you know at least two values. The rest is simple algebra.
