Why the net resistance increases in series connection?
series network consists of components i.e resisters connected end to end. since their is only one path for the flow of current. but potential drop across each resister is different. so thats the reason that series network has maximum resistence then the highest resister in combination. the same amount of current passes through each resister.
How does a resister pack work?
resister is nothing but a 'clay' which will reduce the flow of current. There by limiting the volt.
Where is resister used?
To impede the flow of current
Does potential difference change with change in resistance?
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
How can you determine the resistance of a current?
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
Is current produced with out potential difference?
No.
Current is proportional to the potential difference and inversely proportional to its?
Current is proportional to the potential difference and inversely proportional to resistance. Ohm's law: Current equals voltage divided by resistance
The difference between charge and current?
Charge is potential, current is flowing.

How does voltage produce current?
Voltage across two terminals mean there exists a potential difference, and when the circuit gets closed, due to this potential difference the current flow.
What is the potential difference across a 1500 ohm resistor carrying a current of 0.075 A?
Potential Difference across a resistor is given by, Potential Difference = Resistance * Current = 1500 * 0.075 = 112.5 Volts
If the potential difference between two points increases what will the current do?
If the potential increase and resitance remain the same ,the current will encrease
Where is resister used?
To impede the flow of current
What is the potential difference across a resistor that dissipates 24 W of power and has a current of 3 A?
Work it out yourself. PD=P/I, Where PD=Potential Difference, P=Power & I=Current
What happens to the current when a switch is on?
It moves to equalise a potential difference
