In electronics, R or resistance is calculated by dividing the voltage by the current, or I/E
Here's a good Ohms law chart; http://www.the12volt.com/ohm/ohmslaw.asp
To calculate the resistance for a slip ring motor, there is an equation that must be solved. This is Torque = S/R. S is the slip of the motor and R is the resistance of the motor.
V = voltage across the resistance (Volts) I = current through the resistance (Amps) R = resistance of the resistance (Ohms). I = V / R. Power dissipated (heat produced) by the resistance = I2R = V2/R
1/R= 1/R+1/R+1/R.... The first R is total resistance and the other R's are the resistances of the individual resistors
we can calculate the current in a commmon electrical circuit by this formulae i.e,I=V\R where i is the current flowing in the conductor, R is resistance , V is the voltage.. THE FORMULA IS CORRECT but the term conductor does not suffice an explanation since a conductor is low in resistance R= resistance not conduction.
E = I x R Thus R (in ohms) = E (in volts) / I (in amps)
to fine I (current) when you have R (resistance) and V (voltage) you use the formula: I = V / R
The unit of resistance is the Ohm, and by applying a small voltage to your wire, and measuring the resultant current, you may calculate the resistance.From the formula I = E/R, where R = resistance in Ohms, E is the voltage in volts, and I is the current in amperes.
V=IR so, R=V/I or resistance = Voltage / Amps Therefore, the resistance (R) = 9 volts / 3 Amps answer: 3 Ohms
Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
By Ohm's Law.... Voltage equals Current times Resistance (V=I*R) So if given the voltage and resistance of a system and applying algebra I=V/R .
V = I x R V = voltage, I = Current, R = Resistance or it can be calculate like this V = P / I V = Voltage, P = Electric Power, I = Current
You have to use the v=i * r or I = v/r or r= v/i when v stands for voltage, i stands for current and r stands for resistance. To get the total resistance, add up all the resistance of each load. you must use a wire table wire comes solid with strands for the same Lents two solutions.
Where V=stands for voltage, I=stands for current and R=stands for resistance. voltage=current multiplied by resistance so, by transposition, resistance=voltage divided by current. or R=V/I, R=9/3 The resistance is 3 ohms.as by ohm's law, v=irr = v/itherefore the resistance is 9/3=3 ohms
Resistance calculations are the same no matter what the polarity of applied voltage. R=E/I Resistance (in ohms) = Voltage (in volts) divided by Current (in amperes)
In this case, to get the equivalent resistance, first you use the parallel formula (1/R = 1/R1 + 1/R2) to calculate the equivalent resistors in parallel. Then you calculate the series resistance of this combination, with the other resistor.
One way to calculate current is using ohms law; current equals voltage divided by resistance or: I=V/R Where I is current, V is voltage and R is resistance.
If you are looking for the resistance of each resistor in either a series circuit or a parallel circuit you must measure the current I and the voltage V for each resistor. Then calculate its resistance using Ohms Law R = V / I where I = current (Amps), V = voltage (Volts) and R= resistance (Ohms).
A DMM measures resistance by passing a known current through the object you are measuring and reads the voltage. You can then calculate the resistance using the equation V=I*R. R=V/I So for 1mA and a return voltage of 1V the resistance must = 1 KOhm. R= 1/0.001 = 1000 Ohm
A lamp has two resistances: a 'hot' resistance (its operating resistance) and its 'cold' resistance (its resistance when switched off), and the hot resistance is significantly higher than its cold resistance.You can calculate its 'hot' resistance from its rated power and its rated voltage (assuming that it is being supplied at its rated voltage), by manipulating the following equation, to make Rthe subject: P= V2/RYou will, though, have to measure its cold resistance.
In that case, the resulting (equivalent) resistance will be less than any of the individual resistances. The equivalent resistance is calculated by the formula: 1 / R = 1 / R1 + 1 / R2 + 1 / R3 ... Where "R" is the equivalent resistance you want to calculate, and R1, R2, etc. are the resistance values of the individual resistors.
The formula you are looking for is R = W/I x I.
The equation you are looking for is R = E/I.
Conductance is reciprocal of resistance. Hence, G=1/R. Calculate now
The equation that you are looking for is I = E/R. Amps = Volts/Resistance.
Parallel resistance refers to 2 or more resistors where the input sides are connected together and the output sides are connected together. The formula to calculate it is the inverse of the total resistance of the circuit is equal to the sum of the inverses of the individual resistances. 1/R (total) = 1/R (1) + 1/R (2) + 1/R (3) + …
