What else can I help you with?
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 in a series circuit if one of the resistors is replaced with a resistor having a lower resistance value?
In a series circuit, if one resistor is replaced with a resistor of lower resistance, the total resistance in the circuit decreases. This leads to an increase in the overall current flowing through the circuit.
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?
If the resistor is removed from the circuit, the total resistance in the circuit decreases. This causes the total current in the circuit to increase, which would result in an increase in the ammeter reading.
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 resistor when there are more components?
Adding more components changes how a resistor works. In a series circuit, resistance goes up, slowing current. In a parallel circuit, resistance drops, letting more current flow. The effect depends on how the components are connected.

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 when you use a smaller resistor in place of larger one?
as we can deduce from its name, the resistor "resists" to the current (the movement of the electrons) so as the value of the resistor increases, the current flowing through it decreases. so when you use a smaller resistor, the current increases, however the tension between its poles decreases ( due to the voltage divider law). remember that the shortcircuit is due to the small value of the current , so we need always to have a resonable resistance on the circuit..... but not too high because joule losses we'll be more significant !! hope i've been clear :D

When a resistor is added the current goes down, that is expressed in the equation current= voltage/ resistance
