Does the resistance of heater coil remains same when current flows through it?
Typically resistance rises with temperature.
A resistance of 10 ohms is placed across a 9 volt battery what current flows through the battery?
No current flows through the battery. There is a current through the external circuit. I = E/R = 9/10 = 0.9 amperes.
Normally a high current flows through a short circuit even if there is no change to the voltage. Why is this?
A high current flows through a short circuit even if there is no voltage change because the resistance across the short circuit is zero.
What limits the current that flows through a circuit for a particular appllied DC voltage?
The voltage applied and the resistance across it.
What is the effect of field current on dc motor?
The field current of a dc motor provides the magnetic field that allows the motor to develop a torque when current flows through the armature..
What is meant by resistance of a current?
The resistance of a current is a measure of how difficult it is to push the electrons along.AnswerThere is no such thing as the 'resistance of a current'. Resistance is a characteristic of the material through which a current flows, not of the current itself.

What happens to the current at a junction in a parallel circuit?
In a parallel circuit the current divides when it comes to a junction. Part of the current flows through one branch and the other part flows through the other.When the two branches have the same resistance, the same current flows through each branch.When the two branches have different resistances, a bigger current flows through the branch with the smaller resistance - it's just easier this way!Hope i helped ;)
How does the loading effect of an ammeter in a low resistance circuit compare to the loading effect in a high resistance circuit?
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.
What is the amount of current that flows through an electrical pathway with a resistance of 48 and voltage of 240v?
5amps of current will flow it
A resistance of 10 ohms is placed across a 9 volt battery what current flows through the battery?
No current flows through the battery. There is a current through the external circuit. I = E/R = 9/10 = 0.9 amperes.
How much current flows through a resistance of 300 ohms if the power source is 15 volts?
Ohm's Law Voltage = Current x Resistance Answer is 15/300
Normally a high current flows through a short circuit even if there is no change to the voltage. Why is this?
A high current flows through a short circuit even if there is no voltage change because the resistance across the short circuit is zero.
Why does the cord of an electric heater not glow while the heating element does?
The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.
What limits the current that flows through a circuit for a particular appllied DC voltage?
The voltage applied and the resistance across it.
What does a super conducter do?
It has no (zero) resistance - thus current flows without losses.
