An electrical device draws 4.68 a at 220 v. (a) if the voltage drops by 31%, what will be the current, assuming the resistance doesn't change?

The current will be 3.23 A.

Explanation:

Given that,

Current I = 4.68 A

Voltage V = 220 volt

We need to calculate the resistance

Using ohm's law

Where,

V = voltage

I = current

R = resistance

Put the value into the formula

We need to calculate the current

If the voltage drops by 31%

Voltage will be

Now, the current will be

Hence, The current will be 3.23 A.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
