Maximum Current in AC Circuit Problem

In summary, a 200? resistor is connected in series with a 10.0V AC generator, and the peak current through the resistor is 0.05A for both frequencies of 100Hz and 100kHz. The equation used was V=IR and the question may have been intentionally misleading with the frequency values.

Homework Statement


A 200? resistor is connected in series with an AC generator that produces a peak voltage of 10.0V. What is the peak current through the resistor if the frequency of the source is (a) 100Hz and (b) 100kHz


Homework Equations


V=IR


The Attempt at a Solution


I just plugged in the numbers and I arrive at a value of Imax=0.05A for both part a and part b. Is this correct? I am just uncertain if the question is only trying to lead me astray with the frequency values as they do not seem to play a part in this solution.

Thanks a lot. This question just seemed... Overly simple.
 

Related to Maximum Current in AC Circuit Problem

1. What is the maximum current in an AC circuit?

The maximum current in an AC circuit is the highest value of current that flows through the circuit during one complete cycle of the alternating current. It is typically referred to as the peak current and is denoted by the symbol Imax.

2. How is the maximum current calculated in an AC circuit?

The maximum current in an AC circuit is calculated using the peak voltage (Vmax) and the impedance (Z) of the circuit. The formula for maximum current is Imax = Vmax / Z.

3. What factors affect the maximum current in an AC circuit?

The maximum current in an AC circuit is affected by the voltage of the power source, the impedance of the circuit, and the frequency of the alternating current. Higher voltage and lower impedance will result in a higher maximum current, while a higher frequency can decrease the maximum current.

4. Why is the maximum current important in AC circuits?

The maximum current is important in AC circuits because it determines the amount of power that can be delivered to a load. It also helps in selecting the appropriate components for a circuit to ensure that they can handle the maximum current without overheating or causing damage.

5. How can the maximum current in an AC circuit be controlled?

The maximum current in an AC circuit can be controlled by using components such as resistors, capacitors, and inductors to adjust the impedance of the circuit. Additionally, a fuse or circuit breaker can be used to limit the maximum current to prevent damage to the circuit or devices connected to it.
