for a fixed voltage, the current in an electrical circuit varies inversely as the resistance in the circuit. If a certain has a current of 3.5 amps when the resistance is 110 ohms, find the current when the resistance is doubled.​

Answer:  1.75 amps

Step-by-step explanation:

V (voltage) = I (current) · R (resistance)

              V =    3.5 (110)

                 =   385

When Resistance is doubled, the current is cut in half.

             V = I R

         385 = I (2 · 110)

         [tex]\dfrac{385}{220}=\text{I}[/tex]

         1.75 = I
