Chapter 32: Q. 6 (page 924)

A 200 Ω resistor is connected to an AC source with $ε_{0}$ =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: $I_{o}$ =50mA

Step by step solution

Part(a) Step 1 : Given information

$R = 200 Ω$

$ε_{o} = 10 V$

Frequency =100Hz

Part (a) Step 2: Simplify

Peak current is given by $I = \frac{ε_{o}}{R}$ ,does not depend upon frequency

$I_{o} = \frac{ε_{o}}{R}$

$I_{o} = \frac{10 V}{200 Ω}$

$I_{o} = 0.05 A \Rightarrow 50 mA$

Part(b) Step 1 : Given information

$R = 200 Ω$

$ε_{o} = 10 V$

Frequency=100 kHz

Part (b) Step 2: Simplify

Peak current is given by $I = \frac{ε_{o}}{R^{}}$ ,does not depend upon frequency

$I_{0} = \frac{ε_{o}}{R^{}}$

$I_{o} = \frac{10 V}{200 Ω}$

$I_{o} = 0.05 A \Rightarrow 50 mA$
