A resistor will not change its value, unless the voltage exceeds the designed power capacity of the resistor. As the voltage increases, the current will increase, if the current gets too high it will cause the temperature of the resistor to increase, if the temperature exceeds the power rating of the resistor then the resistance WILL change. If it goes too High in temperature the resistor will open and current will no longer flow. A resistor is used to control current, and indirectly the .voltage depending on the application. Hope This helps. You must use Ohms Law to see the relationship.
If you add a second resistor, the resistance of series circuit will increase.
It is halved. coz voltage=current * resistance
The circuit becomes a pure resistance circuit where current and voltage are in phase with each others.
An electron traveling through the wires and loads of the external circuit encounters resistance.
The net resistance can be found out using the algebraic sums f series and parallel connections. When there is no current flowing in the circuit the net resistance is infinite.
If you add a second resistor, the resistance of series circuit will increase.
The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
The hypothesis of a rheostat is that by changing the resistance in a circuit using the rheostat, the current flowing through the circuit can be varied, thus regulating the output of the circuit.
It shortens
😉
When you increase the resistance in a circuit, the current (amps) in the circuit will decrease. This is because Ohm's Law states that current is inversely proportional to resistance, so as resistance increases, current decreases.
What do you mean by a 'parallel delta' circuit -is there such a connection.
It is halved. coz voltage=current * resistance
In a series circuit, if one resistor is replaced with a resistor of lower resistance, the total resistance in the circuit decreases. This leads to an increase in the overall current flowing through the circuit.
if the resistance is decreased and the current stays the same, then the power decreases.
Flow of current decreases proportionately.
