Question

resistance of motor is 200 ohms and the current maximum is 2.2Amps.find the main voltage supply so it works efficiently​

Answer 1

Explanation:

resistance R= 200 ohm

current I = 2.2amp

voltage V= IR

V= 2.2*200

= 440 volt

Answer 2

Answer :

• Voltage of the motor of resistance 200 Ω and with a current of 2.2 A is 440 V.

Explanation :

Given :

• Resistance in the motor, R = 200 Ω
• Current in the motor, I = 2.2 A

To find :

• Voltage in the circuit, V = ?

Knowledge required :

• The equation for Ohm's law :

⠀⠀⠀⠀⠀⠀⠀⠀⠀V = IR

Where,

• V = Voltage in the circuit.
• I = Current in the circuit.
• R = Resistance in the circuit.

Solution :

By using the first equation of motion and substituting the values in it, we get :

⠀⠀=> V = IR

⠀⠀=> V = 2.2 × 200

⠀⠀=> V = 22/10 × 200

⠀⠀=> V = 22 × 20

⠀⠀=> V = 440

Therefore,

• Voltage in the circuit, V = 440 V
