Question

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

Answer: 1.75 amps

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)

`(385)/(220)=\text{I}`

1.75 = I
