Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{6}{19} = \frac{x - 12}{2x - 2}$

Step 2: Solve for x

Cross-multiply: $\displaystyle 6(2x - 2) = 19(x - 12)$
Distribute: $\displaystyle 12x - 12 = 19x - 228$
Isolate x terms: $\displaystyle -12 = 7x - 228$
Isolate x term: $\displaystyle 216 = 7x$
Isolate x: $\displaystyle \frac{216}{7} = x$
Rewrite: $\displaystyle x = \frac{216}{7}$

an arc welder provides 250 amps of current when operating with a voltage of 40 volts. what is the power required by this welder

FinnZ [79.3K]

The power(P) of the circuits is the product of the voltage (V) in volts and current(I) in amperes.
P = IV

Substituting the known values to the equation,
P = (250 amps) x (40 volts) = 10,000 Watts

Thus, the answer is 10,000 Watts.
