Question

Solve the following automotive-services problem.

Voltage = 80v
Current = 40 amps
Resistance =

Answer 1

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=(v)/(r)`

or

`r=(v)/(i)`

lets plug in our values

`r= (80)/(40)`

`r=2`

Resistance is measured in ohm denoted by the symbol Ω

Hence the answer is 2Ω or 2 ohms
