As current is the rate of flow of electric charges
- As I=Q/t
so,there must be free electrons for the flow of electric current in a circuit.Then when voltage is applied at the terminals of circuit the free electrons acquire an average velocity called as drift velocity in the opposite direction to that of electric field (-E).Now the free electrons modify there random motion and a steady current begin to flow in a circuit.
What else can I help you with?
The total current that flows through a circuit is the same as the current that flows through each individual resistor connected in series?
True
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 ;)
What term best describes an electrical circuit in which no current flows from the power source through the control component load and conductors?
A cold circuit
How much current flows through a circuit if the resitance is 4 ohms and there is a12 volt battery?
3 Ampere
What is full load-current in primary?
This is the current flowing in the primary circuit when full-load current flows in the secondary circuit.
What flows through a complete circuit?
Current flows through a complete circuit.
Is current constant through a circuit?
Yes, in a closed circuit, the current is constant and flows continuously through the circuit.
True or false The total current that flows through a circuit is the same as the current that flows through each individual parallel sub-circuit?
True
What device used to open a circuit if too much current flows through it?
A circuit breaker is a device used to open a circuit if too much current flows through it.
What is a path through which electric current flows?
"circuit"
What flows through an electric circuit?
An electrical current.
What is the electric circuit where current flows through all parts of the circuit?
complex circuit
The total current that flows through a circuit is the same as the current that flows through each individual resistor connected in series?
True
Do You measure current across a circuit?
A current flows through, not across, a circuit. And, yes, you can measure it using an ammeter.
Is somthing that flows through an electric circuit an eletrical current?
Yes. Current consists of electrons flowing in a circuit.
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 flows in a circuit to generate a current?
Electricity flows in a circuit to generate a current.
