Answer:

Direct Variation

• y=kx
• k=y/x

The amperes ais the independent variable while voltage is dependent.

• amperes = a
• voltage = v
• constant = k

so the equation is :

• a = kv.

---------------

First step. find the constant of variation.

"when 5 volts are applied the current is 20 amperes" , v=5 , a= 20

• a = kv
• k = a/v
• k = 20/5
• k = 4

the constant of variation is 4. hehe

then we will answer the current when 15 volts.

• a = kv
• a = 4 × 15
• a = 60

60 is the current or amperes when 15 volts are applied.
