Question

An electric motor is operated in a domestic circuit (220 V) that has a current rating of 7A . What result do you expect in this case? Explain.

Answer 1

Answer:

It should have a resistance of r=v/i=220/7 ohm =31.4 ohm

Answer 2

Answer:

R = 31.42 Ω

Explanation:

We have been given ,

V = I × R

Where ,

V = Voltage

I =  current

R = Resistance

Therefore

Resistance R =  $\dfrac{V}{I}$

R =  $\dfrac{220}{7}$

R = 31.42 Ω

Resistance is the opposition that an electrical device has to flow of electrical current

All device have some resistance . A resistor is a device  that has a particular resistance

We have been Resistance is 31.42 Ω
