Given 220 volts 15 amperes 700 rpm and 0.8 ohms what speed will it run if a resistance is connected in series with supply voltage assume the motor is taking the same current?

Most probably, it won't even run or it will run for a while and then burn out, a motor that run 700rpm is an 8 pole induction motor, the only way to get it to run slower or faster is to change the supply frequency, say you want it to run at 350 rpm you have to change the supply frequency from 50Hz to 25Hz

What is the equation of resistance?
Ohm's Law: Resistance in ohms is voltage in volts divided by current in amperes.
How many amperes of current will flow in a circuit if the voltage difference is 9 V and the resistance in the circuit is 3 Ω?
Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
How is current related to resistance in a circuit?
Ohm's law: voltage is current times resistance. Restating this; current is voltage divided by resistance, so increasing resistance would decrease current.
Why does higher applied voltage with the same resistance results in more current?
Ohm's law: Voltage = Amperes times Resistance. This means that increasing voltage while keeping resistance the same must result in an increase of current.
How can calculate resistance for negative dc voltage?
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)
What is measured in amperes a current voltage or an Resistance?
Electrical current is measured in amperes.
What is the current in a copper wire that has a resistance of 3 ohms and is connected to a 9-volt electrical source?
3 amperes. Ohm's law: Voltage is ohms times amperes.
How do you Calculate the voltage of a battery if the resistance is 20hms and the current is 0.35 amperes?
Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
What is the resistance of a 120-W incandescent lamp connected to a 120-V power supply?
Power (watts) = current (amperes) * voltage (volts) Current (amperes) = voltage (volts)/resistance (ohms) 120 watts = current * 120 volts current = 1 ampere 1 ampere = 120 volts/resistance resistance = 120 ohms
What is the generator's voltage if the motor has resistance of 28 ohms and the current is 3.8 amperes?
Ohm's Law: Voltage is resistance time current So, 28 ohms and 3.8 amperes means 106.4 volts.
What is the equation of resistance?
Ohm's Law: Resistance in ohms is voltage in volts divided by current in amperes.
What the equation of resistance?
Ohm's Law: Resistance in ohms is voltage in volts divided by current in amperes.
What is the current when a voltage of 36 volts is applied to a circuit with a resistance of 6 ohms?
Six amperes. Use Ohm's law: the current is the voltage divided by the resistance

If a circuit has a resistance of 4 ohm's how much voltage is needed to produce a 1.4 current in the circuit?
Voltage across a resistance = (resistance) x (current through the resistance) =4 x 1.4 = 5.6If the ' 1.4 ' is Amperes of current, then the required voltage is 5.6 volts.
