Question

Solve the following automotive-services problems based on the examples shown previously.

Voltage = 18 v
Current = 36 amps
Resistance = ?

0.5
2
18
54

Answer 1

The correct answer is option A , 0.5

`0.5`

Explanation:

We know that,

Voltage is the product of current flowing through a conductor in amperes and its resistance

`Voltage = current * resistance\\18 V = 36 Amperes * Resistance\\Resistance = (18 V)/(36 Amperes) \\= 0.5 Volt/Ampere\\= 0.5 ohm\\`

Answer 2

resistance = volts / amps

18/36 = 0.5
