Chapter 32: Q. 6 (page 924)

A $200 Ω$ resistor is connected to an AC source with $\in_{o} = 10 V$ . What is the peak current through the resistor if the emf frequency is (a) $100 H z$ ? (b) $100 k H z$ ?

Short Answer

Expert verified

Result is:

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

Step by step solution

Part(a) Step 1: Given information

We have been given that $R = 200 Ω$ and $ε_{o} = 10 V$

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

We have been given that $R = 200 Ω$ and $ε_{o} = 10 V$

Part(b) Step 2: simplify

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

$I_{o} = \frac{10 V}{200 Ω}$

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