We have the Voltage v = 80 volts
Current i = 40 amps
We need to find the resistance r
The Ohm's law states that the current in any circuit is directly proportional to the voltage and inversely proportional to the resistance
which gives the formula
![i=\frac{v}{r}](https://tex.z-dn.net/?f=%20i%3D%5Cfrac%7Bv%7D%7Br%7D%20%20)
or
![r=\frac{v}{i}](https://tex.z-dn.net/?f=%20r%3D%5Cfrac%7Bv%7D%7Bi%7D%20%20)
lets plug in our values
![r= \frac{80}{40}](https://tex.z-dn.net/?f=%20r%3D%20%5Cfrac%7B80%7D%7B40%7D%20%20)
![r=2](https://tex.z-dn.net/?f=%20r%3D2%20)
Resistance is measured in ohm denoted by the symbol Ω
Hence the answer is 2Ω or 2 ohms
No solution because -9 +9 = 0 and 4x does not equal 3.5x.
I have a solution here wherein instead of A(3) it is A(4):
<span>Plugging the numbers into the equation we get 4x4x3.14 which is 50.24
</span>
I hope you could use my method for solving the A(4) in solving the A(3)
