Ideas for experiment on Ohm's Law Works???

i have to do this experiment 2morrow about Ohm's Law !!!!!!!!!!! and we have to show that it works!!!!!!!!!!!!

i have no idea for the experiment

and also we have to use these equipment:

multimeter
set of thick wires
circuit board
lamp- 3
batteries
 
Ohms law states that the current (I) is directly propotional to the voltage (V) impressed between two points in the circuit and inversely proportional to the resistance (R) between the points.

FORMULA:

I = V/R

In your experiment,

1) The circuit board and wires will be your circuit path (current passes thru this wires and board)
2) The lamp is your resistance (R)
3) The batteries will be your voltage (V) source
4) The multimeter will be used to determine the actual resistance, voltage and perhaps even current (I).

Perhaps your instructor will instruct you to get the total resistance of the circuit (Total, meaning, wire and circuit board resistance and the lamp resistance) with multi meter while the lamp is connected to the circuit board.

At the same time measure the actual impressed voltage (V) when the lamp is connected and switched on.

Upon recording the resistance and voltage, you can now calculate the current I with the formula.
