State both meanings for the word "pound". Explain.
British pound = currency (libra)
American pound = unit of weight
List the two types of voltmeters and explain their differences.
analogue voltmeter = lower accuracy, used to measure high voltages
digital voltmeter = higher accuracy, used to measure very small volatges
List the symbols used for current, voltage, and resistance, respectively.
Current = I, Voltage = E or V, Resistance = R
