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.
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
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
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.
to fine I (current) when you have R (resistance) and V (voltage) you use the formula: I = V / R
E = I x R Thus R (in ohms) = E (in volts) / I (in amps)
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
V=IR so, R=V/I or resistance = Voltage / Amps Therefore, the resistance (R) = 9 volts / 3 Amps answer: 3 Ohms
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
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 .
Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
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.
