Peak current through the resistor is given by:
From the above equation, the peak current is inversely proportional to resistance.
Therefore, if the resistance is doubled, the peak current will be halved.
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?
