Question

Solve the following automotive-services problem.

Answer 1

2 Ω
80v/40A=2Ω
formula is R=V/A

Answer 2

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

$i=\frac{v}{r}$

or

$r=\frac{v}{i}$

lets plug in our values

$r= \frac{80}{40}$

$r=2$

Resistance is measured in ohm denoted by the symbol Ω

Hence the answer is 2Ω or 2 ohms
