Which three statements are all true about how to set up the voltmeter? (You should refer to the experimental hints on Blackboard.) i) Connect the voltmeter to one electrode using the COM connection on the voltmeter. ii) Connect the voltmeter to one electrode using the Voltage connection on the voltmeter. iii) Connect the voltmeter to one electrode using the 20A connection on the voltmeter. iv) Set the voltage to read direct current. v) Set the voltage to read alternating current. vi) Connect the battery. vii) Be sure to include the 10ohm resistor.

true i, ii, vi

Explanation:

The voltmeter is an instrument to measure the potential difference, which is formed by a galvanometer and a series resistor, to measure the voltage this must be counted in parallel to the circuit that is with each tip at one end different from the element to be measured.

Let's review the claims

i) True. This is one side of the voltmeter.

ii) True. This is the other ends of the voltmeter

iii) False. This is to measure current

iv) False. The selector must be in continuous voltage

v) False. The voltage selector continues

vi) True. This is an element to measure

vii) False. The resistors are an internal part of the voltmeter and do not have to be connected externally

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
