Why do the readings differ for increasing and decreasing values of the incandescent lamp voltages?
...what readings? current? voltage? power? lux?
Can you measure power with a volt meter?
No. A voltmeter measures potential difference (voltage). To measure power, a wattmeter is required. On the other hand, for a d.c. circuit only, you could use a voltmeter and an ammeter, and multiply their readings in order to calculate the power of a load.
When checking resistance does the power have to be off?
Short answer: yes. Most modern multimeters will not be damaged by external power when measuring resistance. But they will give erroneous readings. It is best to remove the power and disconnect the measured resistance from the larger circuit. A multimeter determines resistance by applying a small voltage, and measuring the resulting current. If the resistor has an external voltage source, then it will interfere with the measurement. Furthermore, if the resistance is connected to a larger circuit, then the resistance of this larger circuit will also be involved.
How is a vrs sensor tested with a DVOM?
Back probe both wires of the sensor and use an AC voltage setting or your readings will be bad
How kvar is calculated?
There are various ways in which you can determine the reactive power (in reactive volt amperes) of a load. From the practical point of view, you can use a voltmeter and an ammeter and use the product of their readings to determine the apparent power (in volt amperes) of the load, and a wattmeter to determine the true power (in watts) of the load, then find the vectorial difference: (reactive power)2=(apparent power)2-(true power)2
What controls sensors?
Nothing :d Not so sure that's true. Improper voltage or short circuits can affect the sensors functions which can give false readings. Always check your circuits before replacing your sensors.
How could u tell were the epicenter is located with 2 seismograph readings?
The difference between the two seismograph readings could tell you where the epicenter is located.
What can you assume about the amount of water vapor in the air if there is no difference between wet- and dry-bulb readings of a psychrometer?
nothing is the difference

How does the zero error affect your measurements?
it will create a consistence difference in your readings as it is a systematic error.
Why was heat measured by the thermometer in the drawer?
To observe the difference between the thermometer readings in the drawer and in direct sunlight.

It is saturated.
What was the difference between the thermometer readings in the drawer and in direct sunlight?
The temperature of the thermometer in the direct sunlight was higher than the thermometer in the drawer.
