What is the Difference between voltage controlled device and current controlled device?
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
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
What si th difference between a series and parallel circuit?
The primary difference between a series and a parallel circuit is how many pathways the current has to travel in. Let's look at both of them and see what's up. In a simple series circuit, there is only one path for current. The current must flow through every component in the circuit.
Which electrical protective device is designed to detect a difference in a current between circuit wires and interrupt the circuit and stop the flow of electricity?
A resistor is a device designed to detect difference in current and stop the flow of electricity. On most every type of electric engine or circuit has a resistor.
What is the difference between a current transformer and a voltage transformer?
A current transformer step downs the current in a power circuit to a lower amperage. A voltage transformer steps down the voltage in a power circuit, typically to 110 volts AC for residential and business use.
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.
Why phase difference exists between voltage and current in ac circuit?
because of the reactances in the circuit
When does current stop flowing in a circuit?
Current flows in a circuit when there is a difference in electronic potential between two points.
What is the difference between GNP at current price and GNP at constant price?
it is the same
How can in series connection current remain constant while the voltage change while by ohm's law voltage is directly proportional to current?
If the voltage between the ends of a series circuit changes, the current in thecircuit definitely does not remain constant. The current does change by the samefactor as the voltage.The current at every point in the series circuit is the same current.
What is the Difference between voltage controlled device and current controlled device?
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
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 resistance decreases in a circuit when the voltage remains constant the current will?
Current will increase
If resistance goes up does current go down?
At constant temp.& pressure,on the same circuit,with potential difference unchanged,current reduces if resistance increases.(Ohm's law).
What is difference between seiries curcuits and parallel circuits?
A: In a series circuit the current remains the same In a parallel circuit the current may divide to satisfy the branches of the loads,
The constant flow of electrons through a complete circuit?
That is called electrical current.
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
