Solutions

Chapter 2, Problem 2.10QAP
Interpretation Introduction

(a)

Interpretation:

Resistance of the resistor should be calculated by using the equation related to Ohm’s law.

Concept introduction:

The equation for Ohm’s law is given below.

V=IR

Here, V is voltage, I is current, and R is resistance.

Interpretation Introduction

(b)

Interpretation:

This is a condition with low frequency. So the loading error equation related to low frequency should be considered.

Concept introduction:

At low frequencies, loading error is given by the following equation.

Er=RSRL+RS×100%

Where,Er=Percentage error in the current measurementRS=Resistance of the resisterRL=Resistance of the voltage measuring device
