What is the maximum insulation resistance reading on a 800A busbar?
infinite
What will happen if the reading of ammeter a2 after passing through 30 ohm resistance if reading of a1 is 3A after passing through 20 ohm resistance if both are parallel to each other?
5 A
Why does the voltage reading of 110 circuit is less than expected?
A load or a resistance
What happens to the ammeter reading when a lamp is added to a circuit which contains two cells and a lamp in series?
Assuming the new lamp is in series, the ammeter reading falls because the total resistance has increased. By how much depends on how the lamp resistance depends on voltage. If the lamp is added in parallel to the first, then the ammeter reading doubles.
If you want to measure a current greater than the full scale deflection of the constructed ammeter in this case should the resistance in parallel with the galvanometer be increased or decreased?
A: the resistance should be decreased to 1/2 its value for half scale reading or use any ratio [ decrease] to obtain a correct reading.
Why it is essential for voltmeters to have a very high resistance?
if the resistance of the meter is low that will act as a parallel load effecting the reading. If the meter can be made with infinite resistance then the meter will not effects the actual reading.
What reverse resistance reading should diodes have when under test with an ohmmeter?
Reverse resistance should be infinite.

What will happen if the reading of ammeter a2 after passing through 30 ohm resistance if reading of a1 is 3A after passing through 20 ohm resistance if both are parallel to each other?
5 A
When the leads of the meter are touched together a nd the meter is set to measure resistance what should the resistance reading be?
Zero ohms.
What reading material is a common reason for resistance to receiving help is?
pride
When the front gas tank is unhook out of a ford 150 how could the gas meter still be reading full?
Gas gauges work based on electrical resistance. When the float in the tank is moved up or down by the fuel level, it changes the resistance and the gauge reads differently. Some gauges read full if resistance is high and full is resistance is low. If I understood the question, you unhooked the gauge and it is reading full, that is because you have opened the electrical contacts to unlimited resistance. But, if the gauge was always reading full, before you disconnected it, and that was the root of your problem, then the wire could be shorted to chassis ground and the gauge is reading the resistance of the entire truck.
If you are using a multimeter as an ohmmeter and you get a reading of maximum resistance what does that tell you about the circuit you are measuring?
Did you mean "maximum RESISTANCE" or "maximum VALUE"? If the former, then, you have a ZERO reading, meaning there is high resistance, and no electrical connectivity. If the latter, you have a ONE (or 100%) reading, meaning there is NO resistance, or absolute electrical connectivity. As an analogy, if you turn on a plugged-in, working, lamp, then it has NO resistance, such that power flows easily through the cord; if it didn't turn on, then there IS resistance, such that no power flows, possibly due to broken wire, bad switch, burned-out bulb, or blown fuse.

A load or a resistance
What will happen to the ammeter reading if the resistance is increased?
The current decreases due to I=V/R. The ammeter reading will decrease as R is increased.

Assuming the new lamp is in series, the ammeter reading falls because the total resistance has increased. By how much depends on how the lamp resistance depends on voltage. If the lamp is added in parallel to the first, then the ammeter reading doubles.
When a multimeter is set to measure resistance what reading would you expect when the probes aren't touching?
If the test leads are not in contact with anything, the needle or pointer of an analog meter will be resting at the left most position. This is represents an infinite amount of resistance, or an "open circuit"; it is also safe to say there is the no continuity, or path between the black and red probes.
