electrical resistance
1. The high-resistance paper has a resistivity of 1:25 Ωm. How
do your values compare? What
are possible causes for discrepancies between the known value and
your calculated values?

“resistance” and “resistivity”?
2. What is the rated resistance of a resistor coded with
the color bands: Brown-Gray-White? (Google resistor color
codes)
3. Voltmeters measure electric potential; ammeters
measure electric current. Which of these two types of measuring
device is likely to have an extremely high internal resistance?

You are the audit manager of Chestnut & Co and are reviewing
the key issues identified in the files of two audit clients.
Palm Industries Co (Palm)
Palm’s year-end was 31 March 2015 and the draft financial
statements show revenue of $28·2 million, receivables of $5·6
million and profit before tax of $4·8 million. The fieldwork stage
for this audit has been completed.
A customer of Palm owed an amount of $350,000 at the year-end.
Testing of receivables in April...
