The current, I, varies inversely to the resistance, R. If the current is 250 milliamperes when the resistance is 5 ohms, find the current when the resistance is 20 ohms.
a) 124.5 milliamperes
b) 50 milliamperes
C)62.5 milliamperes
d) 1250 milliamperes

C

Step-by-step explanation:

First find the voltage which is current times resistance. Convert milliamperes to amperes. Divide 250/1000 because amperes are 1000 times smaller. That results in 0.25. So multiply 0.25 A by 5 ohms. That is 1.25. Now divide 20 by 1.25 which is 0.0625. Convert that to millamperes by multiplying by 1000. That gives you 62.5 millamperes.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
