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.
No, ammeters have a low internal resistance. This is so that when they are put in series with a circuit, they change the circuit's operating characteristics as little as possible.Contrast this with voltmeters, which do have a high internal resistance, and which are intended to be placed in parallel with the circuit they are measuring.Use the link below to the related question on why ammeters have a low internal resistance and read through that information to see why things are the way they are.
yes, batteries have high internal resistance. The higher the resistance the lower power you get out of the batter. Therefore if you no power you have very high resistance.
No, the resistance of an insulator is very high.
There is no such a thing as infinite resistance but it could be a very high resistance.
no
Resistance of a short circuit is actually very low, ideally it is 0 Ohms. In practice the resistance of a short circuit will be equal to whatever the resistance of the short circuited wires is, which is typically very small. So if you substitute very small resistance value R into Ohm's Law(I = V/R), you will get a very high current flowing. Where V=voltage,I=current.
ln reverse biase high resistance and in forward biase very low resistance
'Loading effect' applies to voltmeters, or to multimeters when set to measure voltage. It describes the change in a circuit's resistance when the resistance of the voltmeter is taken into account. It's effect is to cause the resulting measuredvoltage to be different from the actual voltage which would appear without the voltmeter connected. The loading effect is minimised by ensuring that the internal resistance of the voltmeter is significantly higher than the resistance of that part of the circuit to which it is connected. For general voltage measurement, this is usually the case anyway, but when measuring circuits which, themselves, have very high resistance care must be taken over the choice of voltmeter to be used.
A perfect insulator (which does not really exist) would have an infinitely high resistance. Good insulators provide very high resistance to current flow, on the order of tens of megohms and up.
Voltage and resistance are distinctly different quantities. I can say some voltages have very low resistances (and high currents), such as when you drop a hair dryer into the tub. You're question as it is written does not make sense.
A substance that pours very slowly has a high viscosity. This means that the substance has a high resistance to flow and does not easily change shape.
The current flowing in a circuit is said to be very small when it is in the range of microamperes (10^-6 A) or even lower. This low current can be indicative of high resistance or very low power consumption in the circuit.
