Power dissipated is ( I2 R ).
If you triple the voltage across a constant resistance, it will dissipate
9 times as much power as it did before the voltage changed.
In a circuit with constant voltage, the relationship between current and resistance is inversely proportional. This means that as resistance increases, the current flowing through the circuit decreases, and vice versa.
If resistance is doubled in a circuit with constant voltage, Ohm's Law (V=IR) states that current (I) would be halved since the voltage is constant. This is because the relationship between resistance and current is inversely proportional.
A variable resistor can be used to control the current in a circuit by adjusting its resistance. By changing the resistance value, the amount of current flowing through the circuit can be regulated.
As long as the voltage between the ends of the circuit remains constant, the current through the circuit is inversely proportional to the total effective resistance of the circuit.
If the voltage in a circuit were doubled, the current would also double according to Ohm's Law (I = V/R), assuming the resistance in the circuit remains constant. This is because current is directly proportional to voltage when resistance is held constant.
If measuring resistance of materials or resistors by themselves(not soldered into a circuit board) resistance is constant. If measuring resistance of a circuit then it could fluctuate with the components functioning in the circuit.
Voltage will be constant. Resistance is dependent on the components in the circuit. Source: Electronics Technician for the US Govt
Ohms' law says if voltage stays constant resistance controls the current flow. Resistance goes up, current goes down. E/I*R.
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.
It is halved. coz voltage=current * resistance
In a circuit with constant voltage, the relationship between current and resistance is inversely proportional. This means that as resistance increases, the current flowing through the circuit decreases, and vice versa.
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
Inversely. As resistance increases, current dereases; given that the applied voltage is constant.
If resistance is doubled in a circuit with constant voltage, Ohm's Law (V=IR) states that current (I) would be halved since the voltage is constant. This is because the relationship between resistance and current is inversely proportional.
If resistance is halved while voltage remains constant, the current will double.
no it is not possibleAnswerYes, by changing the voltage OR the resistance.
No it cant. Voltage = Current x Resistance. So at constant Voltage if the Resistance is increased, Current will reduce
