Voltage, current, and resistance can be related by this formula. V = iR, where I is the current. Assuming that the voltage stays constant, current will decrease. Hope this helps!

What happens if a circuit has no resistance?
Then the voltage in will equal the voltage out. The purpose of a resistor is to reduce the amount of electrical flow of current. You 'short out' the supply and blow a fuse/circuit breaker.
What happens when resistance is varied in a circuit?
A resistor will not change its value, unless the voltage exceeds the designed power capacity of the resistor. As the voltage increases, the current will increase, if the current gets too high it will cause the temperature of the resistor to increase, if the temperature exceeds the power rating of the resistor then the resistance WILL change. If it goes too High in temperature the resistor will open and current will no longer flow. A resistor is used to control current, and indirectly the .voltage depending on the application. Hope This helps. You must use Ohms Law to see the relationship.
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
When a resistor is connected in parallel what happens to the size of current form the battery?
When a resistor is added the current goes down, that is expressed in the equation current= voltage/ resistance
What happens to current in a series circuit?
the current in series will be same..
What happens when more than one resistor is connected to a circuit?
the current flowing in will be low
What happens to the ammeter reading if resistor is removed?
Opening any circuit will stop the current from flowing.
What happens to current in a parellel circuit if a resistor load increases?
Your question needs rephrasing; as it stands, it makes no sense.
What happens to the current in a circuit when one bulb is replaced by two bulbs in series?
current in series always stays the same

What happens to the current in a circuit as a capacitor charges?
What happens to the current in a circuit as a capacitor charges depends on the circuit. As a capacitor charges, the voltage drop across it increases. In a typical circuit with a constant voltage source and a resistor charging the capacitor, then the current in the circuit will decrease logarithmically over time as the capacitor charges, with the end result that the current is zero, and the voltage across the capacitor is the same as the voltage source.

What happens to the current in a circuit if a 1.5 volt battery is removed and is replaced by a 9 volt battery?
Current will go up by a factor of 6 times in that scenario.
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
What happens if a conductor was not metal but yarn?
Yarn is a very poor conductor. I you replaced wire in a circuit with yarn, there would be no current flow.
