A 200 鈩� resistor is connected to an AC source with E0=10 V. What is the peak current through the resistor if the emf frequency is (a) 100 Hz? (b) 100 kHz?

Short Answer

Expert verified

Result is:I0=50mA

Step by step solution

01

Part (a) Step 1 : Given information

R = 200鈩�

蔚0=10V

Frequency=100Hz

02

Part (a) Step 2 : Simplify

Peak Current is given by I=蔚oR, does not depend on frequency.

Io=蔚oR

Io=10V200惟

I0=0.05A

I0=50mA

03

Part (b) Step 1 : Given information

R = 200鈩�

蔚0=10V

Frequency=100 kHz

04

Part (b) Step 2 : Simplify

Peak Current is given by Io=蔚oR, does not depend on frequency.

Io=蔚oR

Io=10V200鈩�

Io=0.05A

I0=50mA

Most popular questions from this chapter

You have a resistor and a capacitor of unknown values. First, you charge the capacitor and discharge it through the resistor. By monitoring the capacitor voltage on a oscilloscope, you see that the voltage decays to half its initial value in 2.5ms. You then use the resistor and capacitor to make a low-pass filter. What is the crossover frequency fc?

a. Evaluate VR in figure at emf frequencies100,300,1000,3000,10000Hz

b. Graph VRversus frequency. Draw a smooth curve through your five points.

An inductor is connected to a 15kHzoscillator. The peak current is 65mA when the rms voltage is 6.0V. What is the value of the inductance L?

A capacitor has a peak current of
