Does the induced emf in a circuit depend on the resistence of the circuit?
The induced emf in a circuit is not directly dependent on the resistance of the circuit. It is primarily determined by the rate of change of magnetic flux through the circuit. However, the resistance of the circuit can affect the current flow and ultimately impact the magnitude of the induced emf through Ohm's law (V = IR).
What does a current in a circuit depend on?
current depends on applied voltage and resistance.
What does the size of a current depend on?
The size of a current depends on the voltage applied and the resistance of the circuit.
Does resistance depend upon current?
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
What would the current flow be if a short circuit is put across the battery's terminals?
That will depend on the internal resistance of the battery. I = E / R Where I is the current, E is the open circuit battery voltage, and R is the internal resistance of the battery.
If you know the current through one resistor in a DC circuit then do you know the current through all the other resistors?
No. Current and voltage are directly proportional to one-another and both are related to resistance by Ohm's law: V = IR or Volts = Current * Resistance So the current will depend upon the voltage and the circuit resistance by rearranging the above equations: I = V/R Meaning that the current will decrease as circuit resistance is increased if the voltage remains constant.
You are just asking that let us assume you have connected 2 or 3 resistors in a circuit and the current flowing through the circuit and from all the resistors will be same but how?
If the resistors are connected in series, the total resistance will be the sum of the resistances of each resistor, and the current flow will be the same thru all of them. if the resistors are connected in parallel, then the current thru each resistor would depend on the resistance of that resistor, the total resistance would be the inverse of the sum of the inverses of the resistance of each resistor. Total current would depend on the voltage and the total resistance
Is the resistance lower if you have a high current?
Lower than what? For the same voltage, a lower resistance means higher current. But beware, the voltage itself might depend on the current - thus - with a fixed resistance if you change the voltage, you will increase the current in the same proportion. Some things become higher resistance if they get hot (a tungsten filament in a lamp). Other things become lower resistance if they get hot (semiconductors). So it can all depend on what kind of circuit you have.
What does the amount of current flowing in each branch of a parallel circuit depend on?
The amount of current flowing in each branch of a parallel circuit depends on the resistance of each branch. The branch with less resistance will have more current flowing through it, while the branch with more resistance will have less current flowing. Each branch acts independently because they provide multiple paths for current to flow.
Why does the resistance of a filament depend on the current?
The resistance of a filament depends on the current flowing through it because as current flows through the filament, it heats up due to the electrical energy converting into heat energy. This increase in temperature causes the resistance of the filament to increase, resulting in a higher overall resistance in the circuit.
What are the different ways to induce current in a coil?
Different ways to induce current in a coil are as given below:(1) If a magnetic field is changed round a coil then an induced current is set up in the coil. It can be done by taking a bar magnet and bringing it closer to the coil or taking it away from the coil.(2) If a coil is moved in a magnetic field, then again an induced current is set up in the coil.(3) If a coil is rotated in a uniform magnetic field, it may also cause an induced current in the coil.(4) If we take two coils and insert them over a non conducting cylindrical roll then on changing current flowing in one coil, an induced current is obtained in the other coil.CommentYou don't induce a 'current' into a coil; you induce a voltage. If that coil is open circuited, then no current will flow. If, on the other hand, the coil is connected to a load, or its opposite ends short-circuited, then the induced voltage will cause a current to flow. Remember, current will only flow if there is a load, or short circuit, and the value of the current will depend upon the value of the induced voltage and the resistance of the load or short circuit.
What condition are necessary for a current to be present in a circuit?
The only two things needed for current flow are electromotive force or voltage and a conductor. The amount of current flow will depend on the "Resistance" in the circuit.
