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.

Describe how a change in resistance would affect the current in a circuit?
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.
In a series circuit when adding light bulbs does the current change?
Yes. The current is inversely proportional to the resistance. I = V / R where I is current, V is voltage, and R is resistance. Adding light bulbs adds resistance. Current is constant throughout a series circuit; it doesn't change no matter what. Voltage changes.
How is a thermistor used in a baby incubator?
A thermistor changes its resistance when the temperature changes. This means as the room temperature changes the current in the circuit containing the thermistor changes. This change in current is detected by the heater circuit, turning the heater on and off.
What is the difference between continuity and resistance check?
Continuity is checking for a completed circuit including a short circuit. Checking resistance would be checking in ohms resistance of a circuit, motor windings or an open circuit.
What happens to amps when you increase the resistance of a circuit?
If you don't change the voltage between the ends of the circuit,then higher resistance in the circuit means lower current (amps).
Why isn't resistance 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.
In a AC parallel circuit which is constant voltage or resistance?
Voltage will be constant. Resistance is dependent on the components in the circuit. Source: Electronics Technician for the US Govt
Explain how changing the resistance in a circuit chages the current?
Ohms' law says if voltage stays constant resistance controls the current flow. Resistance goes up, current goes down. E/I*R.
How the current in a circuit changes if the voltage in the circuit is decreased and the resistance remains the same?
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.
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
If the voltage applied to a circuit remains constant and the resistance in the circuit is increased the current will?
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
How does current vary with the resistance in the circuit if the voltage is constant?
Inversely. As resistance increases, current dereases; given that the applied voltage is constant.
Will doubling the resistance in a circuit halve the current if voltage is held constant?
If resistance is halved while voltage remains constant, the current will double.
Can you increase current in a circuit without change in resistance and voltage?
no it is not possibleAnswerYes, by changing the voltage OR the resistance.
The amount of current in a circuit can what by increasing the amount of resistance present in the circuit?
No it cant. Voltage = Current x Resistance. So at constant Voltage if the Resistance is increased, Current will reduce

If the resistance decreases in a circuit when the voltage remains constant the current will?
Current will increase
