What else can I help you with?
What is the resistance of a circuit that takes a current of 0.5A when the voltage to the circuit is 40v?
The formula you are looking for is Ohms = Volts/Amps. R = E/I.
How can you make a current smaller in a circuit?
Taking some bulbs out of the circuit!! (I think :P) Taking some bulbs out of the circuit!! (I think :P) Use Ohm's law I = E/R. Add some values and check it out. You use the formula V = IR (where V and E are the same thing, voltage. I is the current. R is the resistance). If you add more resistance then your current will be lower. I would suggest looking at parallel and series resistance so that you can understand equivalent resistance.
What happens to the resistance of the circuit when you add resistances in parallel?
Adding a resistance in parallel to another resistance will reduce the equivalent resistance. Parallel Equation: R1 = 10Ω R2 = 20Ω Req = R1R2/(R1+R2) = (1/R1+1/R2)-1 Req = 10•20/(10+20) = 6.67Ω
What is the formula to find resistance in conductors?
For DC circuits: R = l*p / A R - resistance l = length of the conductor p = electrical resistivity A = the cross sectional area Calculating for AC, and especially three phase power becomes much more complicated. If you need to know more for AC, let me know specifics.

What is meant by calculate the equivalent resistance of the circuit from the measured potential difference across the battery and the current through the battery is there a formula for this?
In a complex circuit with various elements (resistors, capacitors etc.) and one battery, the various circut elements contribute to draw a certain amount of current "I"from the battery at some terminal voltage "V". The "equivalent" resistance of the various circuit elements is that resistance "R" which will draw the same current , at the same terminal voltage, as the complex circuit. So to find "R" you simply imagine replacing the complex circuit with "R" by attaching "R" across the terminals of the battery and use Ohms law to find "R" , demanding "I" and "V" are the same. So then R = V/I.
