Does the magnetic field increase or decrease if the current is decreased?
An increase in an electrical current will cause magnetism to increase but a decrease in an electrical current will cause magnetism to decrease.
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
What happens to the voltage in a series circuit when more loads are added?
A: assuming a infinite current source the current will increase accordingly
Will current increase if the voltage in a circuit is increased?
Ohm's Law states Voltage = Current x Resistance. Hence if voltage is increased and resistance is constant, current will increase proportionally to the rise in voltage.
How does the increase or decrease of potential difference affect the flow of the electric current?
Increase or decrease in potential results in the change in direction of the flow of electric current.
What happens to the current carrying ability of a wire when the temperature increases?
the current will increase
When a wire is made smaller the resistance increases. what happens to electric current?
increase
When a wire is smaller the resistance increases What happens to the electrical current?
increase
What happens to the amount of current in a series circuit as the number of batteries increase?
it increases
What happens to the current in a circuit if the resistance is increase?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
What is the electomagnet in a motor called?
Armature
Why is soft material is preferred to make electomagnet than hard?
I assume you mean "soft iron" ... so that it quickly loses its magnetism when the current flow stops.
What happens to voltage when current is increased?
current is decreased Depends of the circuit or device: in a stepdown transformer: power in= power out, V x I = V x I , Increase voltage in (power remaining constant) you current output will increase.
If the current increases what happens to resistance?
An increase in current will only affect resistance if it causes the temperature of the conductor to change. For pure metallic conductors, and increase in temperature will cause an increase in resistance.
Slowly increase the current value from 0 to 60 amps. Describe what happens?
110+40
When you plug in more appliances in your home why does the current increase?
That happens when the appliance supplied by the outlet is switched off.
What happens to the electric current in a wire when voltage is increaced?
If the load resistance is constant, then increasing the voltage will increase the current by the same proportion -i.e. doubling the voltage will double the current.
