Time constant of an RC circuit increases if the value of the resistance?
Increased The time constant of an "RC" circuit IS RC. So it's directly proportional to 'R' and also directly proportional to 'C'.
If you change a bulb in a circuit and the current decreases what is different about the new bulb?
Use Ohm's law that states that, the current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. I = E/R.
How can you increase a current in a wire?
Ohm's law. Current is directly proportional to the applied emf and inversely proportional to the resistance in the circuit.
How Michael Faraday discovered electromagnetic induction?
Move a magnet into a coil, and a voltage is induced into that coil, causing a galvanometer to deflect. Withdraw the magnet, and the galvanometer will deflect in the opposite direction, indicating that the induced voltage depends upon the direction of motion of the magnet.
How many hz is a 110 volt circuit?
Frequency is independent of voltage magnitude. It depends upon type AC or DC.
What is Newmanns law?
It suggests that :- An EMF is set Up in circuit when the magnetic flux linking the circuit is changed in any manner.The magnitude of this EMF is proportional to the time rate of flux linkage with circuit.
Why is it capacitance does not affect current in a Direct Current circuit?
Capacitors resist a change in voltage, proportional to current and inversely proportional to capacitance. In a DC circuit, the voltage is not changing. Therefore, after equilibrium is reached, there is no current flowing through the capacitor.
Current in a circuit is inversely proportional to?
In a circuit , current is inversely proportional to the resistance.
How we calculate magnitude of current in circuit?
It is nothing but how much current or voltage taken in the circuit. It is known as Magnitude.
Why should you use a current probe with a multimeter whenever you need to?
get into tight places,measure high-magnitude currents,monitor currents at a remote location,open a circuit
What is working principle of inductor?
A changing current through an inductor induces a voltage into the inductor, the direction of which always opposes the change in that current.So, in a d.c. circuit, an inductor will oppose (not prevent) any rise or fall in current, although the magnitude of that current will be determined by the resistance of that inductor, not by its inductance.In an a.c. circuit, because the current is continuously changing both in magnitude and in direction, it acts to continuously oppose the current due to its inductive reactance. Inductive reactance is proportional to the inductance of the inductor and the frequency of the supply. The vector sum of the inductive reactance of the inductor and the resistance of the inductor, is termed the impedance of the inductor. Inductive reactance, resistance, and impedance are each measured in ohms.
In the electrical circuit the higher the voltage the lower the?
Amps Ohm's law states the current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.
What happens to circuit if its resistance is doubled?
as per ohm law current is directly proportional to the applied voltage and inversely proportional to the resistance now u can calculat according to the formula by by putting the considered value and then by changing the values according to the question u will get the result to Analise the difference.
Do resistors lower volts or amps?
Current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.
Time constant of an RC circuit increases if the value of the resistance?
Increased The time constant of an "RC" circuit IS RC. So it's directly proportional to 'R' and also directly proportional to 'C'.
If you change a bulb in a circuit and the current decreases what is different about the new bulb?
Use Ohm's law that states that, the current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. I = E/R.
When is an electric circuit opened?
An electric circuit is opened whenever a part of it is not connected to anything.
