The resistance remains constant. The voltage would change, in accordance with Ohms' law, with a change in current.
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.
The voltmeter has an internal resistance, which should be as high as possible. As this resistance draws current from the circuit under test, it will affect circuit operation. This is more pronounced in a high impedance circuit because the current drawn flows through higher resistances.
by adding the the resistances in series the total resistance of the circuit increses and thus the crunt flowing in the circuit decrese. Ans 2 . the current in series circuit of constant resistance will always be the same . It will not effect the current .
Reliable, simple and safe. Heat can be regulated by changing the resistance in the circuit.
The ammeter does affect the flow of current in a circuit, however, the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. It is connected in series.
If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.
Flow of charge: Electric current is the flow of electric charge through a conductor. Voltage: Voltage is the driving force that pushes the electric charge to move in a circuit. Resistance: Resistance is the opposition to the flow of electric current in a circuit, determined by the material and dimensions of the conductor.
An ammeter has a finite resistance which is inserted in series with the rest of the circuit, increasing the total resistance and decreasing the current. A good ammeter has a very low resistance, so it shouldn't affect the circuit noticeably.
Three appliances that use the heating effect of electric circuits are electric stoves, electric heaters, and toaster ovens. These appliances utilize the electrical resistance in a circuit to generate heat for cooking or warming purposes.
Since internal resistance of the ameter will increases the resistance of the circuit. Thus decreasing the current giving an errorenous reading.
it will cause a Short Circuit
The resistance factors to the current flow in the circuit is what causes the heating effect in a circuit. This resistance usually comes from the load that is connected to the circuit. For example a baseboard heater is a completely resistive load and the result of the heating of the device can be used to heat a room in the home.
