How does increasing the number of cells in a parallel circuit affect the current?
by adding resistance in parallel more current is bound to flow
What will happen when we change value of load resistance in transformer?
When the value of the load resistance in a transformer is changed, it will affect the current flowing through the circuit. Increasing the load resistance will decrease the current, while decreasing the load resistance will increase the current. This change in current will in turn affect the voltage across the load and the efficiency of the transformer.
You are monitoring electric current in a circuit. you notice the voltage increasing this mean's that?
Ohm's Law states that the current (I) flowing in a circuit is directly proportional to the applied voltage (E) and inversely proportional to the circuit's resistance (R).I = E/RAnother way of stating Ohm's Law is that the applied voltage (E) is directly proportional to both the current (I) and the resistance (R).E = IxR.So, if the voltage (E) is increasing, then either:if you know the resistance (R) is staying constant then the current (I) must be increasing - which you would see because you are monitoring it! or, if the current (which you are monitoring) is actually staying constant, then, for the voltage to be able to increase:the circuit's resistance must be increasing orthe increasing voltage could be caused by a combination of both increasing current and increasing resistance!
How does loading effect affect flow of current?
Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.
How do resistance behave in parallel circuit?
in a parallel circuit resistance decreases increasing the current.
How does the increasing the resistance affect the current?
Increasing resistance decreases current.
Do additional resistors affect current in a series circuit?
Yes, additional resistors affect current in a series circuit by increasing the total resistance, which decreases the total current.
How does increasing the number of cells in a parallel circuit affect the current?
by adding resistance in parallel more current is bound to flow

Would increasing the resistance increase electric current?
no
1 What is the effect caused by the ammeter resistance when an ammeter is inserted into a circuit to measure the current?
An ammeter has a finite resistance which is inserted in series with the rest of the circuit, increasing the total resistance and decreasing the current. A good ammeter has a very low resistance, so it shouldn't affect the circuit noticeably.
The amount of current in a circuit can what by increasing the amount of resistance present in the circuit?
No it cant. Voltage = Current x Resistance. So at constant Voltage if the Resistance is increased, Current will reduce

What will always increase voltage?
increasing resistance and keeping current constant
How is current related to resistance in a circuit?
Ohm's law: voltage is current times resistance. Restating this; current is voltage divided by resistance, so increasing resistance would decrease current.
How does loading effect affect flow of current?
Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.
Why does the resistance of a filament bulb depend on the current in the bulb?
The resistance of a piece of wire changes with temperature. In a filament bulb the wire is heated to about 3000 degrees C so a large change in resistance can be expected. A 240 v 105 w halogen bulb has a cold resistance of 35 ohms, but when running its resistance is 549 ohms.
