b. 3.33
c. 6
d. 120
user:
what circuit quantity is measured by connecting a meter's test leads in series with an energized component?
a. voltage
b. current
c. power
d. resistance

1. A. 4.5 W

The power in a circuit is given by:

where V is the voltage and R is the resistance.

In this circuit, we have:

is the voltage

is the resistance

Therefore, the power in the circuit is

2. D.

The total resistance of resistors connected in series is the sum of the individual resistances:

In this case, we have 6 identical resistors with same resistance . Therefore, the total resistance will be

3. B. Current

An ammeter is a device which is put in series with another component of the circuit, in order to measure the current through it. In fact, in a circuit, components which are connected in series have the same current flowing through them: therefore, the reading of the current in the ammeter will corresponds to the same current which is flowing to the other component.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
