Question

your weld settings are 17.5 volts and 125 amps. use ohms law to calculate how much resistance is in your welding circuit.

0.014 ohms
0.14 ohms
107.5 ohms
10.75 ohms

volts (v)
=
amps (i)
x
resistance (r)

Explanation:

Identify given values and formula

$$
LATEXBLOCK0
$$

Rearrange formula for resistance

$$ R = \frac{V}{I} $$

Calculate resistance value

$$ R = \frac{17.5}{125} = 0.14\text{ ohms} $$

Answer:

• (A) 0.014 ohms
• (B) 0.14 ohms (Correct answer)
• (C) 107.5 ohms
• (D) 10.75 ohms
