This is a very technical electrical question that may be difficult to understand without further study. But adding appliances to an outlet is the same as adding resistance in parallel. Adding resistance in parallel, the resistance of the circuit goes down. That is why you get more current flow.
By contrast, adding resistance in series increases the resistance of the circuit and therefore reduces current, all else being equal.
If you add a second resistor, the resistance of series circuit will increase.

It is halved. coz voltage=current * resistance
The circuit becomes a pure resistance circuit where current and voltage are in phase with each others.
An electron traveling through the wires and loads of the external circuit encounters resistance.
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 you add a second resistor, the resistance of series circuit will increase.
The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
Increasing the length of wire in a series circuit increases the overall resistance in the circuit, which reduces the current flowing through the circuit. This results in a decrease in the brightness of any connected bulbs or the speed of any connected motors, as the components receive less energy due to the increased resistance.
It shortens
the circuit is broken.

When you increase the resistance in a circuit, the current (amps) in the circuit will decrease. This is because Ohm's Law states that current is inversely proportional to resistance, so as resistance increases, current decreases.
What do you mean by a 'parallel delta' circuit -is there such a connection.
The voltmeter will register the volts, the ammeter will either explode or blow a fuse since it has a very low resistance and is designed to be used in series to measure the current flowing through it.
