12) The electric current, C, varies inversely as the resistance, R, of a conductor. If the current is 2 when the resistance is60, what is the current when the resistance is 240?+

Respuesta :

The electric current, C, varies inversely as the resistance, R

C =k/R

If C=2 and R=60, solve for k

2 = k /60

2 (60) = k

120 = k

When R = 240:

C=120/R

C = 120/240

C= 0.5
