Equivalent resistance of a series circuit is the sum of the resistance of all appliances. The formula is R=R1+R2+... where R is equivalent resistance, R1, R2 and so on is the resistance of the individual appliances.

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 formula for calculating the total resistance in a series circuit with threeresistors?
RSeries = SummationI=1toN (RI) Simple answer; add them up.
The total resistance in a parallel circuit is the smallest resistor in the circuit?
No, it is less. Use the formula:1/R = 1/R1 + 1/R2 + 1/R3...Where R is the total (equivalent) resistance for the parallel circuit,and R1, R2, etc. are the individual resistance.No, it is less.

What is an example of mass resistance?
An example of mass and resistance is voltage, we know that the following is the formula for calculating voltage: V = IR where R is the resistance and I is the current.
What is the equivalent resistance through the enire circuit of 90 volts?
Not enough information. In the case of simple circuits, usually you would add resistances that are in series, and use a slightly more complicated formula for resistance that are in parallel. You CANNOT determine an equivalent resistance known only the voltage. However, if you know the total current, you can divide the voltage by the total current to get the equivalent resistance.
Using ohm's law what is the formula to find the resistance in a circuit?
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
What is the method for calculating amperes and current?
A formula that is often used is Ohm's Law: voltage = current x resistance.
Is resistance additive in a series circuit?
No. The reciprocal is additive. The formula for the equivalent resistance, in parallel, is 1/R = 1/R1 + 1/R2 + 1/R3... where R is the total equivalent resistance, and R1, etc. are the individual resistances in parallel. Note that the equilalent resistance will be less than any of the individual resistances.
What is the formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
