Problem: A resistor is connected across an oscillating emf. The peak current through the resistor is 2.0 A. What is the peak current if: a. The resistance R is doubled?b. The peak emf ε0 is doubled?c. The frequency ω is doubled? 

FREE Expert Solution

Peak current through the resistor is given by:

i=ε0R

a.

From the above equation, the peak current is inversely proportional to resistance.

Therefore, if the resistance is doubled, the peak current will be halved.
