Explanation / Answer
How would you connect a multimeter to measure the current through the 8 ohm resistor?
in series
a)explain why the multimeter is connected in this way
ammeter has a low resistivity therefore it makes no potential difference.
b)what design feature of a good multimeter allows you to connect in the way indicated without appreciably
affecting the current through the 8 ohm resistor?
low resistivity

How would you connect a multimeter to measure the voltage across the 8 ohm resistor.
in parallel
a)explain why the multimeter is connected in this way
voltmeter has a high resistivity and therefore no current will pass through it.
b)what design feature of a good multimeter allows you to connect in the way indicated without appreciably affecting the current through the 8 ohm resistor?
high resistivity
