5 ohms in parallel with 20 ohms is 4 ohms. 4 ohms across 200 volts is 50 amperes. However, resistance is a function of temperature, so the 4 ohms will probably be higher, reducing the current. How much depends on the temperature coefficient of the loads.
A resistance 'network' consists of a number of resistors connected together in series, or in parallel, or in series-parallel, or as a complex circuit. A 'complex' circuit is one that is not series, parallel, or series-parallel.
Depends. What did you want to measure? If it's voltage drop across the incandescent element, then you had better hook up your infinite resistance voltmeter in parallel with the lamp.
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
A parallel branch is a current path. In general, current follows paths, voltage drops across components, and resistance is the voltage divided by current of specific circuit elements.
in the series circuit elements are one behind the other ie +ve terminal of one element is connected to the -ve of other element of the circuit whenever in parallel circuits the elements are parallely connect ie all +ve terminal are connected at a point and all -ve terminals of the elements are connected at a point.
In principle, it is infinite. I have not connected a parallel circuit in ages.
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
An ammeter has low resistance (ideally no resistance) because it is placed in series with other circuit elements to detect how much current is flowing. If it is placed in parallel with a component it will short-circuit it. That is a bad thing.

The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.

If two or more circuit elements are connected in series, the current must pass through each of them in turn. If two or more circuit elements are connected in parallel, that means there is a "fork in the road". In this case, part of the current will pass through one element, and part, through another one.

Series circuit: elements are connected one after the other; the current (the electrons, or other charge carriers) has to pass through each of the elements in turn. Parallel circuit: elements are connected in such a way that part of the current will pass through one circuit element, part through the other.
If it is connected in series with a circuit then it might raise the resistance too high and fail the system. Parallel connection is a circuit is probably the best bet you have.
When resistors are connected in parallel to the same voltage source, the overall resistance in the circuit decreases. This is because the current has multiple paths to flow through, reducing the total resistance that the current encounters.
Voltmeters are connected in parallel in a circuit.
