increasing the voltage increases the current. this is because when you increase the voltage you make the pressure that is pushing on the current (which is making it move) greater, therefore increasing it.
<<>>
Ohms law states that, the current is directly proportional to the applied (EMF) voltage and inversely proportional to the resistance in a circuit.
The formula you are looking for is I = E/R. You supply some figures for Voltage (E) and Resistance (R).

What happens if you turn off the electric current in the solenoid?
If you turn off the electric current in the solenoid, the solenoid quits pulling its armature.
What happens to the amount of current in a series circuit as the number of batteries increase?
it increases
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.
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 effect does increasing the current have on solenoid?
it will produce a stronger magnetic field.
What happens if you turn off the electric current in the solenoid?
If you turn off the electric current in the solenoid, the solenoid quits pulling its armature.
What happens if you increase the current in an electomagnet?
As current increases, the electromagnet strength will increase.
How can you strengthen a solenoid's magnetic field?
Think of the four C's- Add more Coils- Add an iron Core- Add a stronger Current- Make the coils Closer
What happens to the current carrying ability of a wire when the temperature increases?
the current will increase
What if a current passes through solenoid If yes then what happens in the whole process?
Yes. DC can pass through. As it passes through then solenoid would act as if a bar magnet.
When a wire is made smaller the resistance increases. what happens to electric current?
increase
Increasing the number of loops per meter in the coils of a solenoid is one way to?
Increasing the number of loops per meter in the coils of a solenoid is one way to increase the wire's electric current.
When a wire is smaller the resistance increases What happens to the electrical current?
increase
Which factors affect the magnetic strength of a solenoid which is carrying an electric current?
Factors affecting the magnetic field strength of a solenoid are: - length of the solenoid - diameter of the solenoid - current through the coil around the solenoid - number of turns of the coil of current around the solenoid, usually turns of wire - material in the core
How could you increase the strength of a solenoid?
by increasing the number of turns of solenoid........
Is a solenoid a coil of wire that has a current?
YESA solenoid is a coil of wire, which turns into a magnet when a?current?flows through
What happens to the amount of current in a series circuit as the number of batteries increase?
it increases
