What happens to the strength of an electromagnet when the voltage in the coils of the solenoid is decreased?
The greater the current in the coil, the stronger the magnetic field will grow. Conversely, lowering the battery voltage decreases the current, weakening the field.
What happens to the thermal energy of an object as temperature decreases as it increases?
it decreases because when an object is moving as the temperature decreases the object decreases
What happens to the power in a circuit as the current increases?
P=VI If current (I) increases then P will increase proportionally. That is, assuming that voltage (V) remains constant. If voltage decreases and current increases or vice versa, proportionally then P will remain the same.
As the wavelenght decreases what happens to the waves frequency?
As wavelength decreases, frequency increases
What happens to the speed of a wave if the frequency decreases and the waveleNgth increases?
the wave decreases.
What happens to the current as the resistance decreases?
it increases
What happens when you decrease the current in an electromagnet?
When you decrease the current in an electromagnet, the magnetic field decreases.
What happens when a part of a parallel circuit is disconnected?
current decreases and resistance increases
What happens in a circuit when the resistance gets greater?
Flow of current decreases proportionately.
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 happens to the current in the circuit if the resistance is increased?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
Will you get a electric shock when the negative terminal of the dc power supply is grounded and the positive terminal is held by us?
Only if we are also in contact, directly or indirectly, with ground. By ohm's law, current is voltage divided by resistance. Conductance is the inverse of resistance, so current is voltage times conductance. No conductance - no current.
Why leakage conductance is neglected in overhead lines?
The shunt conductance is due to leakage currents flowing across insulators and air. As leakage current is considerably small compared to nominal current, it is usually neglected, and therefore, shunt conductance is normally not considered for the transmission line modeling.
What happens to the power of an electric circuit of the resistance is decreased?
if the resistance is decreased and the current stays the same, then the power decreases.
Why direct current has no conductance?
Direct current is measured in units of voltage and current. Conductance is the inverse of resistance. The two systems are not related to each other, except through Ohm's Law. The question does not make sense. Please restate the question, with more detail as to what you are trying to ask.
Why use AC to measure ionic conductance and why not dc current?
in order to avoid electrolysis
What is a measure of how easily current will pass through a material?
resistance conductance or 1/resistance
