If the ratio of voltage to current is constant, then the circuit is obeying Ohm's Law. If the ratio changes for variations in voltage, then the circuit does not obey Ohm's Law.
Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.
If you are referring to a simple circuit, you could add resistance throughout it. Increased resistance means decreased current flow yet the same voltage.
Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
In a circuit , current is inversely proportional to the resistance.
if the resistance is decreased and the current stays the same, then the power decreases.
Increases the total resistance
resistance is the opposition to the flow of an electric current, therefore the current will decrease as the resistance increases. Resistance also creates heat. This is how the light globes in a circuit light up.
Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.
The resistance is increased, the voltage across each bulb is decreased and the current through the circuit is reduced.
A rheostat is a variable resistor that can increase or decrease the resistance in a circuit. By increasing the resistance in the circuit, the rheostat limits the flow of current, causing it to become higher in the parts of the circuit where the resistance is lower.
This question follows Ohm's law which states, "Current is directly proportional to the applied EMF (voltage) and inversely proportional to the current in the circuit. <<>> decreased
The current in the circuit will be decreased by half. Ohm's law states V=IR so, I=V/R. If R is doubled, then I= V/2R.
Inductance and resistance are both properties that affect the flow of electricity in a circuit. Resistance opposes the flow of current, causing energy to be converted into heat. Inductance, on the other hand, resists changes in current flow by storing energy in a magnetic field. In an electrical circuit, inductance and resistance can interact to affect the overall behavior of the circuit, with inductance causing delays in current changes and resistance dissipating energy.
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
If you are referring to a simple circuit, you could add resistance throughout it. Increased resistance means decreased current flow yet the same voltage.
A thermister is a device that changes resistance depending on temperature. A photo resistor changes resistance based on light. Both of these could be used with an amplifying circuit to vary current flow.
